Frequently Asked Questions

Why is the route 1 (east main st) bridge being replaced?

The bridge has reached the end of its lifespan and is in poor condition.  

How long will CONSTRUCTION last?

Work on I-95 and Route 1 will continue through the summer. Construction work that will be completed includes:

  • Rebuilding of the section of the I-95 median that was removed

  • Reconnection of utility lines (electric, water, gas) that are located under the bridge deck

  • Rebuilding of wing wall sections and abutment rehab

  • Construction of sidewalk, parapets (bridge rail) and fencing on Route 1 bridge

  • Milling and paving of Route 1 and Northbound and Southbound I-95

During this construction there will be lane closures on I-95, mostly Northbound and sometimes Southbound, from 8 pm to 6 am Monday through Thursday. The contractor may also work Friday night if the project has been delayed by rain.

What is the Route 1 detour route?

During construction weekends, traffic will be diverted off of Route 1 onto Courtland Avenue and Hamilton Avenue. For more information, see Route 1 Detour Map.

How long is the Route 1 detour route?

The detour route is one mile. Travel on city streets will be slower than on state Route 1 as some of the route is narrower, with stop controls.

Is there a pedestrian detour?

Yes. Pedestrians can use an existing walkway that connects Seaside Avenue to Courtland Circle, Blatchley Road, and Route 1. The pedestrian detour adds about a half-mile to the walking route. For more information, see Route 1 Detour Map.


Yes, the route will be detoured and riders should allow extra time for travel. See travel notice and relocated stops here.

What is Accelerated Bridge Construction (ABC)?

ABC is an innovative building technique that significantly reduces the amount of time required to replace a bridge. Bridge components are built ahead of time and then fit together during construction. This off-site work allows for speedier project completion, reducing impacts on the traveling public. For this project, the two bridge spans will be built in their entirety and then fit into place, one span over the weekend of June 1-2, the second span on the weekend of June 7-8. If this bridge were replaced using traditional construction methods, the project would take approximately two years.

Has CTDOT used ABC construction before?

Yes. CTDOT previously used ABC to replace two I-84 bridges in Southington and Route 8/25 in Bridgeport. The method used for the Southington project is similar to what will be done in Stamford. View time lapse video of Southington project below.


What is the cost of the project?

The total contract price for replacing the bridge is $15 million.

How is the bridge being paid for?

The State of Connecticut is providing 100% funding for this project.

Who is completing the construction?

CTDOT has contracted with O&G Industries for this project.

Will I be able to watch the bridge move?

Check out the Gallery for photos and videos of the bridge move and a time lapse video of the bridge construction.

What type of outreach was done to notify travelers about the project?

The outreach team has attended or held meetings with Stamford civic and neighborhood groups and

conducted personal outreach to Stamford businesses along Route 1, local officials, religious institutions, hospitals, the Towns of Darien, Greenwich and City of Stamford, large employers in the area including WWE, Chelsea Piers, and NBC Sports, and various special events happening in Stamford.

Prior to the closure weekends, residents and businesses surrounding the project will be receiving mailers with details on the closure schedule. Prior to and during the closure weekends, there will be electronic message signs on all Connecticut highways and on major routes in New York State bordering Connecticut to alert motorists about travel delays that will likely encourage travelers to avoid the construction area.

The project has also been covered by various media outlets including television, radio, and newspaper. The CT Department of Transportation will continue to collaborate with the media to obtain maximum publicity for the project, especially on construction weekends when significant travel delays are expected In addition, social media will be used to let travelers know about project updates during the month of May and during construction weekends.
