State transportation officials say delays are expected to continue through Friday because of bridge resurfacing on I-95.
The work is actually occurring on the highway overpass over Lowell Street ion Peabody, but backups have extended back into Danvers each morning.
The work started on Sunday night and is expected to continue through Friday, according to Michael Verseckes, a state Department of Transportation spokesman.
The bridge work is scheduled to wrap up by 5 p.m. on Friday, Aug. 24 at 5 p.m. The work started late on Sunday night.
The work is happening just north of the split to Route 1 southbound and that ramp will remain open throughout the work.
To start the week, the two lefthand lanes had been closed while the work was ongoing "to allow work crews to complete bridge deck repairs and paving operations."
State officials said the work would be contained to the southbound side but did not say when work may shift to other areas of the bridge.
"The work will be completed in two phases with the first phase focusing on the left lanes and the second phase focusing on the right lanes," the state DOT said in its traffic alert.
Real Time Traffic Management signs have also been put up to let drivers know how long it will take to get through the work zone.
Drivers have complained on Twitter this week about the morning backups caused by the word. The construction has also attracted the attention of local television traffic reporters.
The state DOT did say that, if possible, drivers should seek alternate routes.
The work is part of a $5.7 million project on that section of I-95 that also includes installing a median guardrail along I-95 between Peabody and Boxford.
