The Connecticut Department of Transportation will replace the Route 1 bridge over I-95 at Exit 9 in Stamford during two weekends in June using an Accelerated Bridge Construction (ABC) process.

I-95 Detour

I-95 traffic will shift at Exit 9 to temporary roadways located at the On and Off ramps to allow for removal and replacement of the Route 1 bridge. Travel will be REDUCED TO TWO LANES IN BOTH DIRECTIONS WITH A SPEED LIMIT OF 20 MPH. These changes will be in effect from 9:00 p.m. on Friday evening to 5:00 a.m. on Monday morning on the weekends of June 1st and June 8th. DRIVERS SHOULD EXPECT LONG DELAYS AND SHOULD TAKE ALTERNATE ROUTES IF POSSIBLE. For more information, see I-95 Lane Shift Detour Map.

route 1 Detour

On bridge construction weekends, the ROUTE 1 BRIDGE WILL BE CLOSED between Courtland Avenue and Seaside Avenue, and traffic will be detoured from Route 1 to Courtland Avenue and Hamilton Avenue. The bridge replacement will occur over two weekends, June 1-2, and June 8-9, weather permitting. On weekdays, between weekend closures, Route 1 will be open to traffic. For more information, see Route 1 Detour Map.

exit 9 Closed

Due to I-95 lane shifts during construction weekends, EXIT 9 WILL BE CLOSED TO TRAFFIC BOTH EXITING AND ENTERING I-95. These detour routes are recommended:

Entering Traffic

Motorists entering I-95 at Exit 9 will need to use alternative access:

  • Travelers should follow detour signs to Exit 11

Exiting Traffic

Motorists exiting I-95 at Exit 9 will need to use alternative access:

  • Travelers should use Exit 11 and follow detour signs to Exit 9

accelerated bridge construction

ABC is an innovative building technique that reduces the amount of time required to replace a bridge. For this project, bridge components are currently being constructed on a site adjacent to the bridge, and will be fit into place over only two weekends. This off-site work will allow for drastically quicker project completion, while also reducing impacts on the public. If this bridge were replaced using traditional construction methods, it would take two years during which time Route 1/East Main Street’s 17,000 daily travelers would have to cope with one-lane travel. CTDOT previously used ABC to replace two I-84 bridges in Southington and on Route 8/25 in Bridgeport. View time lapse photography of Southington project here.
