State and local officials will hold a ceremony Wednesday to break ground on a $255.5 million rehabilitation of the Longfellow Bridge.
The project, which is funded through the Patrick Administration’s Accelerated Bridge Program, will refurbish the historic bridge connecting Boston and Cambridge over the Charles River.
According to MassDOT, the three-and-a-half-year project will address the bridge’s current structural deficiencies, upgrade its structural capacity and bring it up to modern code, including improving multi-modal access and bridge-to-city-street connections to meet accessibility guidelines.
The repairs and modifications will be consistent with the historic character of the bridge and comply with environmental standards, officials said.
Wednesday's ceremony starts at 11 a.m. at Lederman Park on the Boston side of the river. MassDOT Secretary and CEO Richard A. Davey and others will attend the event.
