Weekend Closure and Detour of I-95 in Stamford Scheduled to Begin on Friday, May 31, 2019

The Connecticut Department of Transportation is reminding motorists that the first of two scheduled weekend closures and detours of I-95 in Stamford at Exit 9 is set to begin on Friday, May 31, 2019.  The closures are necessary to facilitate the installation of two new bridge structures carrying Route 1 over I-95. MOTORISTS ARE STRONGLY ADVISED TO AVOID THE AREA DURING THE CLOSURE TIMEFRAMES TO AVOID HEAVY TRAFFIC DELAYS.


Closure Details

The first weekend closure will occur on Friday, May 31, 2019:

  • 6 PM - Exit 9 on-ramps closed and Route 1 reduced to one lane

  • 9 PM - Closure of the off-ramps and the closure of Route 1 at the bridge (between Courtland and Seaside Avenues)

  • 11PM - I-95 will be closed at Exit 9, with traffic diverted to temporary roadways using the highway on and off-ramps

Both I -95 and Route 1 will be re-opened to traffic by 5 AM on Monday, June 3.

The second scheduled weekend closure will occur on Friday, June 7, 2019, following the same pattern used for the first closure, with Route 1 and I-95 re-opened by 5 AM on Monday, June 10.


Construction Update

The two new bridge spans have been completely formed and are ready for installation. Six hundred and twenty-eight cubic yards of concrete weighing over 1.5 million pounds was used to build the two bridge spans. About 32 miles of rebar was installed within the newly constructed bridge spans, and new structural steel was used to create the new bridge superstructures.  Each individual span to be lifted and set into place weighs between approximately 1.6 million pounds, and 1.8 million pounds. 

In the two weeks leading up the closures, the contractor will be busy preparing the site as well as equipment that will be used to move the bridge spans into place.

There will be live streaming video feeds of construction during the weekends when the bridge is installed on the project website, www.i95exit9.com.

4 weeks until bridge is installed on Route 1 over I-95 at Exit 9, Stamford

In four weeks, the first of two bridge spans on Route 1 (East Main Street) over I-95 at Exit 9 in Stamford will be moved and set in place.

On Friday, May 31 at 11 p.m., I-95 motorists will be detoured onto 2-lane temporary roads in each direction while construction is underway.

Earlier in the evening, Route 1 traffic will also be detoured around the work site onto local roads. I-95 and Route 1 will reopen to through traffic by 5 a.m. Monday, June 3rd.

The following week Friday, June 7, beginning at 11 p.m., the second bridge span will be installed as traffic is detoured again around the construction zone.

In an interview with Tony Aiello of WCBS Channel 2- New York, CT State Police Sgt Robert Derry urged motorists to avoid the area on construction weekends as long travel delays are expected.

Concrete Deck is Poured for Span 2

Last week the construction site was lined with trucks delivering concrete for the first span to be installed over the Northbound lanes of I-95.

Some 328 cubic yards of concrete was poured to form the deck. A couple dozen workers guided the flow of concrete over rebar and vibration equipment was used to remove air pockets before the concrete cures.

The contractor finishes the top of the concrete by making it a smooth surface.

The sidewalk and parapet (green rebar on right) will be poured after the bridge is in place.

The sidewalk and parapet (green rebar on right) was not poured because it would add too much weight to the bridge before lifting it into place. This section of the bridge will be completed in the weeks after the spans are installed.

Weeknight Off-Peak I-95 Lane Closures Near Exit 9 in Stamford


There will be weeknight off-peak lane closures on I-95 northbound and southbound in the vicinity of Exit 9 in Stamford, beginning on March 25, 2019 through mid-April. The lane closures are necessary to remove materials (including guano!) from the Route 1/East Main Street bridge before the bridge spans are demolished in June.

Motorists can expect various lane closures on Interstate 95 north and south between Exit 8 (Canal Streets, Stamford) and Exit 10 (Noroton Avenue, Darien). In addition, one lane of Route 1 between Courtland Avenue and Seaside Avenue will be closed. 

Traffic control personnel and signs will be utilized to guide motorists through the work zone. The regular work schedule for this project is from 8:00 p.m. to 5:00 a.m. (Monday through Thursday evenings).

Governor Lamont visits bridge construction site

On a sunny but brisk March morning Governor Ned Lamont visited the Route 1 Bridge work site to highlight the CTDOT’s innovative constructive methods and importance of investing in transportation infrastructure.

Flanked by local and state officials, construction workers and organized labor leaders, Governor Lamont said "Every day, thousands of commuters use this highway to get to work so they can support their families and maintain a decent quality of life. We must provide Connecticut with a modernized transportation system that works, which requires a sustainable, recurring funding source.”

Connecticut Department of Transportation’s Deputy Commissioner Anna Barry noted, “We are using an innovative construction method that will limit detours to two weekends If traditional construction methods were used on this project, motorists would face delays for two years.”

Crane lifts steel for new bridge span

Bridge steel has arrived!

Structural girders and cross framing have been delivered and assembly has begun on bridge Span 2. The bridge is comprised of two spans, Span 1 crosses over Southbound I-95 and Span 2 crosses over Northbound I-95.  Don’t let names deceive you, even though it is called Span 2, the Northbound Span is being constructed before Span 1.

The cross frames at the construction site

Each bridge span consists of 10 large girders measuring between 113 and 125 feet long, and 63 cross frames bolted to the girders to hold them in place. Each girder weighs approximately 40,000 pounds and each cross frame weighs approximately 1,100 pounds. With all of the girders and cross frames combined, that’s almost half a million pounds of steel per span!

The yellow metal towers sandwiched in between the Exit 9 Northbound On and Off ramps are the foundation of a temporary support system for the construction of the Route 1 replacement bridge. Two bridge spans will be built on top of these towers and, when completed, moved into place.
