The Connecticut Department of Transportation replaced the Route 1 bridge over I-95 at Exit 9 in Stamford during two weekends in June using an Accelerated Bridge Construction (ABC) process.
CONTINUED CONSTRUCTION WORK
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 nights if the project has been delayed by rain.
I-95 LANE REDUCTION
During the summer months 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 nights if the project has been delayed by rain.
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.
