Will there be long delays on I-95 during construction weekends?

Yes. When three-to-four lanes of traffic at highway speeds are reduced to two lanes at 20 mph, it will create long backups. Motorists are encouraged to use alternate routes.

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.

Will the CT Transit 341 Bus route be affected?

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

Can I exit or Enter I-95 at Exit 9 during construction?

No, Exit 9 will be closed to exiting and entering traffic on both construction weekends. Traffic exiting I-95 should use Exit 11 and follow detour signs to Exit 9. For traffic entering I-95, travelers should follow detour signs to Exit 11.

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.

What about emergency response during construction weekends?

Since January, the project team has been meeting with representatives of the CT State Police, City of Stamford Police and Fire Departments as well as police from the Towns of Darien and Greenwich to address safety concerns and emergency response when travel delay is expected. The City, Towns and State Police have developed a staffing plan that will provide extra personnel at key locations on local detours to guide travelers and enable emergency response vehicles to move swiftly through detour areas. In addition, the City of Stamford will station a fire truck and ambulance at Cove Island Park throughout the closure weekends to respond to any emergency that may occur in the Cove neighborhood.

Will I be able to use the Route 1 bridge over I-95 during the week between construction?

Yes. The road will be reopened to traffic by the morning of Monday June 3rd and will remain open until the evening of Friday June 7th.

What type of weather might delay the project?

The project will only be delayed in the case of EXTREMELY high winds and torrential rain.

Will the Courtland Avenue project be completed in time for the weekend closures?


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.

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.

Will I be able to watch the bridge move?

There will not be parking or access for the public at the project site. However, there will be a live stream of the bridge move on the project website. We suggest that you watch from the comfort of your couch instead of coming to the project site.

What type of outreach is being 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 aArea.

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.
