ROUTE 805 (FEDERAL ROAD)
STATE ROUTE 805 IN DANBURY (FEDERAL
For an understanding of the key traffic safety terms "TASR"
and "SLOSSS" that are repeatedly referenced in the
discussions below, be sure to review the "Introduction
to Danbury, CT Traffic" section.
Danburys unsigned State Route 805, the 1.73 miles from
White Street northeasterly to White Turkey Road Extension
(State Route 840), is designated by Conn DOT as a principal
arterial route, the highest of functional classifications.
Then from White Turkey Road Extension to the Brookfield Town
Line the remaining .74 miles of this roadway is designated
as a minor arterial route.
From the Conn DOT perspective, important intersections on
Route 805 will be those at other Conn DOT arterial or collector
designated roadways interacting with it. There are four such
intersections; 1) at the origin of Route 805 at White Street
as a principal arterial to the west and a minor arterial to
the east, 2) with White Turkey Road (Route 840) as a collector,
3) with the I-84 Exit 7 westbound on ramp as a principal arterials,
4) and finally at Nabby Road as a minor arterial route.
One local road name is applied to the entire 2.47 mile length
of Conn DOT Route 805; Federal Road. This road name continues
into Brookfield and on into New Milford along the "Old
Conn DOTs 1999 average daily traffic volumes show 13,300
vehicles on Route 805 along the initial segment from White
Street to Starr Road. From there to Eagle Road the total climbs
to 22,300, then to a high 29,700 for the short segment up
to White Turkey Road, 25,800 from White Turkey Road up to
Nabby Road, and from there to the Brookfield Town Line 21,100.
This is certainly a corridor with significant traffic volumes
and much business activity.
The overall policy is to improve Federal Road intersections
from White Street to the Brookfield Line in accordance with
HVCEOs Planning Bulletin 80 dated 12/1994 and entitled
"Traffic Flow Improvement Plan for Federal Road."
That study documents the need for the northern sector of Federal
Road, from Starr Road northerly to the Brookfield Town Line,
to have a consistent cross section allowing for four thru
lanes of travel, complemented by turning lanes as necessary.
A driveway and curb cut management plan for both the Brookfield
and Danbury portions of Route 805-Federal Road was completed
by HVCEO as part of the 1994 study. It is now a standard in
the Brookfield regulations but has not yet been incorporated
into the Danbury zoning regulations. Traffic safety and capacity
issues on Route 805 are as follows:
1. ROUTE 805 IN DANBURY (FEDERAL ROAD) AT WHITE STREET
Description: (Note that Conn DOTs "eight hundred
series" roads are unsigned by remain state roads nonetheless;
number 805 here is the "Old Route 7") At milepost
.00, the beginning of Federal Road as the continuation of
White Street, the 1995-97 state Traffic Accident Surveillance
Report (TASR) hazard rate was 203% with a SLOSSS designation,
indicating greater concern.
Generally TASR rates over 100% indicate higher than normal
accident rates. When a SLOSSS designation is also given by
Conn DOT to TASR locations over 100% then that location is
a priority for concern.
This location had TASR rates of 69% for 1992-94 and 94% for
1989-91. Thus for these earlier periods safety conditions
here had not yet reached the state of a Conn DOT SLOSSS designation
It should be stated that these useful Conn DOT hazard rating
percentages are not to be considered as factual indicators
of hazard but rather as suggestive of safety problem areas.
These TASR statistics for every segment of every state roadway
in Connecticut can be considered serious when over 100%. Those
over 100% that are determined by Conn DOT to be the highest
priorities have an additional "SLOSSS" designation
(Suggested List of Surveillance Study Sites), as found for
1995-97 on this segment.
The 1994 HVCEO study of Federal Road made recommendations
for this intersection. According to that report this intersection
accommodates todays traffic volumes and should continue
to do so in the future with the addition of a double left
lane eastbound on White Street turning onto Federal Road.
However, it has poor geometry due to the intersection angle
and vertical profile of White Street. Driveways directly at
the intersection exacerbate this geometric problem. A long
term solution would be to realign Federal Road more squarely
with White Street.
2. ROUTE 805 IN DANBURY (FEDERAL ROAD)
FROM SWANSON AVENUE TO STARR ROAD
The initial 1.12 miles of Federal Road has no TASR rates
of concern. This is likely due to the fact that the track
of the Danbury Trunk Railroad paralleling Federal Road on
the east so closely along much of Federal Road as to preclude
But from mileposts 1.12 to 1.44, Federal Road for about one
third of a mile between its intersection with Swanson Avenue
northeasterly to its signalized intersection with Starr Road,
we find a modest TASR rate of 62% for 1995-97. However, the
rate for the earlier period of 1992-1994 was 146% with a SLOSSS
designation. The period 1989-91 had a low TASR of 35%. This
segment will be monitored by HVCEO to determine what pattern
The Danbury Traffic Engineer advised in October of 1999 that
capacity improvements would be needed at the Starr Road intersection.
Additionally, the Regional Transportation Plan recommends
that signals along the northern part of the Federal Road corridor
eventually be interconnected and managed by the City along
with its other interconnected signal systems. Specifications
for this work will be prepared as part of a 2001 HVCEO signal
The 2000 Conn DOT I-84 Plan makes recommendations that may
eventually impact the vicinity of the Starr Road intersection
with Federal Road. While the Route 7 Expressway southbound
off ramp to I-84 eastbound is not directly visible from Federal
Road, due to a relocation someday it may be.
At present that Route 7 Expressway off ramp to I-84 east
joins I-84 on its north side. The Conn DOT I-84 Plan proposes
to shift this merge point to the south side, constructing
a "flyover" or new bridging of I-84 in the process.
If this happens, then the new flyover will hug I-84 on its
south side, which is the vicinity of the Starr Avenue intersection.
Conn DOT further recommends that there be a new connector
road from I-84 eastbound after Exit 7, proceeding easterly
along the south side of I-84, to end over at I-84 Exit 8.
This will necessitate a new bridge over Federal Road, adding
a third to the current two, again in the vicinity of the intersection
of Danburys Federal Road with Starr Avenue.
This new I-84 related eastbound collector could eventually
be modified to include a direct eastbound off ramp to descend
and intersect at grade with Federal Road. Such a major new
connection would provide traffic flow balance to the I-84
Exit 7 westbound on ramp about four tenths of a mile to the
north. There is no such balance now.
The Conn DOT I-84 Plan states that "The connection would
be a relatively steep downgrade although within design standards....
In addition, Starr Road would have to be realigned considerably
to the south...."
Continuing, "At this time, the connection is not included
as part of the long term recommendations at I-84 Exit 7, as
the benefits do not appear to off set impacts. However, the
feasibility of this connection should be revisited as design
and permitting of this alternative are progressed."
3. ROUTE 805 IN DANBURY (FEDERAL ROAD)
FROM STARR ROAD NORTH TO EAGLE ROAD
This segment runs from mileposts 1.46 to 1.64 Federal
Road from Starr Road where a wider cross section begins, northerly
under the I-84 eastbound and westbound bridges to the intersection
with Eagle Road.
This segment cannot be described as truly a four lane cross
section, as some lanes become turning lanes to the north.
It should be noted that Eagle Road serves as a local road
connector over to Commerce Park, the largest employment concentration
in Danbury, also to State Route 806 (Newtown Road), just over
one mile away via Eagle Road.
As an historical note, the Eagle Road at grade railroad crossing
here was a private and restricted crossing before it was upgraded
to a public thoroughfare in the early nineties. This City
of Danbury planning and implementation provided a much needed
connection between roughly parallel Route 805 (Federal Road-Old
Route 7) and Route 806 (Newtown Road-Old Route 6).
Along this almost two tenths of a mile segment accident rates
have been increasing in recent years, with a TASR of 15% for
1989-91, 82% for 1992-94, and then up to 142% with a SLOSSS
designation for 1995-97. Landmarks at the intersection with
Eagle Road include Spencers and Appellees restaurants
and a Brake Center of America shop.
The 1994 HVCEO study of Federal Road made recommendations
for the intersection with Eagle Road. These include adding
onto Federal Roads southbound approach to Eagle Road
a third lane as an exclusive southbound left turn lane into
Adding one lane to the two already existing on the northbound
Federal Road approach to Eagle Road is also justified, to
allow for an exclusive right turn only lane into Eagle Road.
The Eagle Road approach to Route 805 also needs two right
turn lanes, turning to northbound Federal Road, to accommodate
the heavy turning traffic in that direction. There it would
meet two lanes but just ahead one is used as an exclusive
right turn into Route 840, so the cross section of Federal
Road also needs expansion.
As noted earlier this HVCEO Regional Transportation Plan
recommends that signals along this part of the Federal Road
corridor eventually be interconnected. Specifications for
this work will be prepared as part of a 2001 HVCEO signal
4. ROUTE 805 IN DANBURY (FEDERAL ROAD) FROM
EAGLE ROAD TO WHITE TURKEY ROAD EXTENSION
Between Route 805 mileposts 1.65 to 1.72, about 300 feet
of Federal Road from the Eagle Road intersection northerly
to the intersection with State Route 840 (also known as White
Turkey Road Extension), the 1995-97 accident rate was 191%
with a SLOSSS designation, the 1994-96 accident rate was 134%
also on the SLOSSS, while the 1989-91 figure was a more modest
86%; a rising rate.
Also note: on the 1995-97 list the specific intersection
of White Turkey Road Extension (also known as State Route
840) with Federal Road was rated at 187% with a SLOSSS designation,
up from 70% for 1992-94 and 67% for 1989-91. Average daily
traffic volume in 1999 was 29,700 on Route 805-Federal Road
between Eagle Road and White Turkey Road Extension, the highest
volume in the corridor, and 16,200 on Route 840-White Turkey
The 1994 HVCEO traffic study of Federal Road made recommendations
for this intersection, calling for an expansion of the Federal
Road northbound approach to Route 840 to three lanes. One
of the two here now becomes an exclusive right turn lane on
to White Turkey Road Extension, and continuity with the four
thru lane cross section that starts north of White Turkey
Road Extension to the north is needed.
At the White Turkey Road Extension westbound approach to
Federal Road-Route 805, one right turn lane should be added
such that two right turn lanes are provided to accommodate
the right turn on to northbound Federal Road. The turn from
White Turkey Road Extension southbound on to Federal Road
already has two lanes marked exclusively for left turns.
North of White Turkey Road Extension Federal Road for the
first time has a consistent four thru lane cross section that
extends into Brookfield. Just to the north of the intersection
with White Turkey Road Extension, the two bridges carrying
the Route 7 Expressway cross over Federal Road.
An earlier HVCEO Regional Transportation Plan stated that
in order to properly plan for this section of Federal Road
"the feasibility of widening the Route 7 Expressway bridge
overpass abutments to achieve a wider Federal Road cross section
will need to be explored," an expensive proposition.
A minimal cost restriping for narrow lanes was also seen as
Fortunately minor widening was approved here via a State
Traffic Commission permit, such that Federal Roads northbound
left turns into the I-84 Exit 7 westbound on ramp for the
first time have a separate turn and storage lane. Also, that
the nearby intersection of Old Brookfield Road with Federal
Road is now signalized as required by the STC permit. These
improvements were completed in September of 2000.
This new signal was funded by the developer of the proposed
Lexington Mews residential complex on Old Brookfield Road,
with 317 parking spaces qualifying as a major traffic generator
subject to Conn DOT review. To facilitate this signalization,
the driveway to the existing Conn DOT commuter parking lot
on the east side of Federal Road, just beyond the Route 7
Expressway bridge, was relocated slightly so that it is opposite
Old Brookfield Road and its driveway makes use of the new
From the commuter parking lot northward to the signalized
intersection with Nabby Road, the TASR for 1989-91 was 93%,
then for 1992-94 up to 102% with a SLOSSS designation, and
then for 1995-97 down to 47%. landmarks are the large Borders,
Home Depot and Bobs stores.
5. ROUTE 805 IN DANBURY (FEDERAL ROAD) FROM
NABBY ROAD TO STEW LEONARDS NORTH DRIVEWAY
This segment is from mileposts 2.12 to 2.36, Federal Road
from its intersection with Nabby Road northerly to the Stew
Leonards store signalized north driveway. The Stew Leonards
store south driveway serves as a fourth leg to the Federal
Road and Nabby Road intersection.
On this one quarter mile segment the 1995-97 Conn DOT TASR
accident rate was 236% with a SLOSSS designation. The hazard
rate is rising here, as 1992-94 was 99% and 1989-91 was 76%.
The recommendation in the 1994 HVCEO study for Federal Road
at its intersection with Nabby Road and Stew Leonards
main driveway was that "In the future a southbound right
turn lane into Nabby Road should be provided.... Since there
are few left turns, the left turn lane could be eliminated
to lessen the widening for the right turn lane." An Arbys
restaurant is on this corner. This recommendation remains
to be implemented.
Moving further north, the recommendation in the 1994 HVCEO
study for Federal Road at its intersection with the Stew Leonards
north driveway was that "because of the number of left
turns into the site a left turn lane would be very useful."
Regarding this proposal, a Conn DOT memo dated 7/24/1999
stated that "the exclusive left turn lane originally
proposed on State Route 805 westbound into the Stew Leonards
northern driveway has been eliminated from this project. The
additional width necessary to construct this turn lane would
result in the loss of parking and property from adjacent businesses...."Other
alternatives were considered to incorporate the turn lanes;
however, the Department has been unable to find a solution
mutually agreeable to all effected property owners."
6. ROUTE 805 IN DANBURY (FEDERAL ROAD) FROM
STEW LEONARDS TO ROUTE 202 IN BROOKFIELD
This section runs from mileposts 2.38 to 2.75, and is
from the Stew Leonards store north driveway northerly
across the town line to the intersection with Route 202 in
This segment had a SLOSSS designation and TASR rate of 112%
for 1995-97, preceded by a SLOSSS and TASR of 120% for 1992-94.
The period 1989-91 recorded a TASR of 122%.
This segment was widened through the HVCEOs STP-O federal
funding program from 2 to 4 thru lanes in the mid-1990's.
The widening linked existing four thru lane cross sections
on either side. Accident rates on this final segment of Federal
Road in Danbury and into Brookfield will be monitored to determine
the impact of that investment.
