NStar crews postpone work on Congress Street
By Mac Daniel, Globe Staff, and Andrew Ryan, Globe Correspondent
Utility crews have postponed work on Congress Street in downtown Boston this afternoon that could have complicated what may already be a difficult evening commute with the continued closure of sections of the Big Dig.
NStar crews had planned on working in the Financial District on Congress Street between State Street and Post Office Square, but decided to put off the work in light of the city’s other traffic problems.
Driving has been more complicated in Boston since July 10, when concrete ceiling tiles cascaded into the Interstate 90 connector tunnel in nearby South Boston and crushed a car, killing Milena Del Valle, 38. The connector, which links Massachusetts Turnpike with the Ted Williams Tunnel, has been closed since the accident.
City streets, especially around the South Boston Waterfront not far from Congress Street, have been hit hard by the closure as key detours send traffic through the area at Exit 25, which now must handle traffic heading to I-93 and the westbound Massachusetts Turnpike.
Others sections of the Big Dig have closed since the initial collapse as engineers scrutinize the tunnel system. On Monday, engineers discovered three more problem bolts holding up ceiling panels in the westbound Ted Williams Tunnel. The tunnel remains open to traffic, but workers set up a new traffic pattern as they work to secure the panel. Heading east, the Ted Williams Tunnel remained open only to buses and emergency vehicles.
Other work will close two lanes of Interstate 93 south every day this week from 11:30 p.m. to 5 a.m. on the approach to the Leonard P. Zakim Bunker Hill Bridge from the Tobin Bridge on-ramp, through the Tip O’Neill Tunnel to the on-ramp near Essex Street.
Earlier this week, officials postponed the opening of Ramp A – from D Street in South Boston to eastbound I-90 –and have not designated a time when it will be fixed.
