FAIRFIELD COUNTY, Conn. -- The work to replace two bridges that carry I-84 over Marion Avenue in Southington was completed more than 12 hours early, with the eastbound lanes opening at 4:30 p.m. Sunday and the westbound lanes between 7 and 8 p.m., the Connecticut Department of Transportation announced.

“After months of diligent planning, design, stakeholder outreach and around-the clock-prefabrication, I was informed by CTDOT that the project is nearly completed and I-84 eastbound is reopening shortly to vehicular traffic," said Gov. Dannel Malloy." A lot was riding on this project getting done without any problems and with very little inconvenience to the nearly 85,000-plus people that travel on this portion of I-84 every day. This is another great example of ConnDOT thinking outside the box to deliver a major bridge project with as few interruptions as possible for the public."

Beginning last summer, the CTDOT's contractor, Northern Construction, using Accelerated Bridge Construction techniques, prefabricated new bridge superstructures. The old bridges were built in 1963 and were in poor condition, the state said. Without ABC principles, the project could have taken many months or years. But only one weekend closure was required for the replacement and installation of two new 102-foot-long bridges that weigh 2 million pounds each.

“Our agency has consistently looked for better ways to deliver projects while minimizing the impacts to traffic, businesses and local communities," said ConnDOT Commissioner James Redeker. "I’m happy to say that this major project, using ABC technologies, has been a phenomenal success."

The CTDOT has used ABC in the past on a smaller scale, but the replacement of the I-84 bridges in Southington marks the first time that the technique has been used on a large-scale construction project. CTDOT said it will continue to use the technology in other suitbale locations after the success of this major bridge replacement.
