The work to replace the Fore River Bridge on Route 3A has officially begun, but it won’t be finished until 2016, with many motorists and residents of Quincy and Weymouth wondering what to expect over the next few years as the new span is built.

In an effort to address those questions and concerns, state transportation officials are holding an informational meeting on Jan. 15 about the $244 million bridge replacement project. The meeting is open to the public and will be held in Weymouth.
