PITTSFIELD, Maine — The new U.S. Route 2 bridge crossing Sibley Pond has opened for traffic, but there is more work to be done, according to the Maine Department of Transportation.

The bridge, which connects Pittsfield and Canaan, opened a couple of weeks ago, said MDOT spokesman Ted Talbot. A temporary bridge bypass that was constructed alongside the new bridge had been used previously.

Talbot said no more major construction on the new bridge is expected until the spring, when the temporary bridge will be removed. The official completion date is set for October.

The new bridge was needed, said Talbot.

“It was in really, really bad shape,” he said of the old structure. “It was ranked two out of three, with three being the worst.”

The bridge was a design-build project, he said, in which contractors submit their designs and the winner builds it. Lane Construction was awarded the $7.8 million contract.

The initial effort to replace the bridge began in March 2008 with a preliminary plan completed in July 2009. The contract was awarded in July 2010 and construction started in October of that year.
