The Connecticut Department of Transportation (Department) has launched a new website, I95Exit9.Com, marking the start of the public information campaign for the project to replace the Route 1 (East Main Street) Bridge over Interstate 95 at Exit 9, in Stamford.

Utilizing Accelerated Bridge Construction (ABC) techniques, new bridge spans will be built in their entirety, adjacent to the existing bridge (with negligible traffic impacts) and then lifted and moved as one unit into place.
The process of lifting and moving the spans, known as “bridge-moves” will necessitate the detour of I-95 and Route 1 over two weekends — June 1 to 2 and June 8 to 9 — in order to facilitate their installation over the highway and onto the existing bridge foundations.
The new structure will be a two-span bridge, with the one span being replaced the first weekend, and the second span replaced on the following weekend.
During the scheduled weekend bridge-moves, I-95 will be reduced to two travel lanes for each direction, beginning at 9 p.m. on Friday, and ending by 5 a.m. on Monday.
I-95 traffic will be detoured off the highway and back onto the highway utilizing modified Exit 9 on- and off-ramps, allowing the highway to remain open during the operations, with ramp speeds reduced to 20 mph for safety.
Additionally, with I-95 Exit 9 being used as a bypass/detour during the weekend bridge-moves, motor vehicle traffic will not be allowed to enter or exit the highway using Exit 9 — it will be used only for carrying I-95 thru-traffic. And while I-95 will technically remain open during the bridge-moves, motorists will be STRONGLY advised to seek alternate routes.
Route 1 will be closed between Courtland Avenue and Seaside Avenue, and traffic will be detoured from Route 1 to Courtland Avenue and Hamilton Avenue during the bridge-moves.
As the project progresses, the Department will continue to inform and collaborate with all stakeholders, including the general public, towns, cities, businesses, law enforcement and other entities.
