---- — Drivers can expect lots of action on Interstate 93 this week.
Overnight paving is planned in Salem, detours in Londonderry for bridge work and blasting continues in Windham.
There are $160 million in projects along the highway this season from Londonderry through Salem. It’s all part of the $800 million highway widening project.
Jay Levine, I-93 coordinating supervisor for the Department of Transportation, said last month drivers will see “changes constantly out there.”
Bridge work is scheduled tonight through Thursday at the I-93 Exit 5 interchange in Londonderry, if the weather is good.
State transportation officials have announced intermittent detours are planned both from Route 28 and for travelers leaving the highway there between 9 p.m. and 3 a.m.
Minor traffic delays are anticipated.
The $37 million Londonderry project involves construction of four new bridges at Exit 5.
Severino Trucking Co. Inc. of Candia is scheduled to complete work by June 2014.
Last week, blasting prompted temporary daytime closures of a ramp at Exit 3 in Windham for safety reasons, DOT spokesman William Boynton said.
Workers are blasting ledge that is close to the ramp. Blasting will continue daily, Monday through Friday, through April, from 10 a.m. to 2 p.m.
Rolling road blocks are being used to slow southbound traffic on the highway during blasting.
On-ramp traffic at Exit 3 will be temporarily stopped for blasting. There may be extended on-ramp closures due to blasting, DOT is advising drivers.
In those instances, drivers trying to leave Route 111 to go south on I-93 will have the option of either traveling north on I-93 and reversing direction at Exit 4 or using Route 28 to get to Exit 1 south. Drivers should follow the blue I-93 South emergency route signs to do so.
There are two projects in Windham.
R.S. Audley Inc. of Bow is working on a $35 million I-93 widening contract that also involves relocation of Route 111. E.D. Swett Inc. of Bow has a $12 million bridge project.
Night paving is scheduled overnight tomorrow through Thursday on I-93 north from the Salem welcome center to the Exit 1 ramp. Traffic will be restricted to one lane from 7 p.m. to 5 a.m.
Last week, crews were installing a concrete barrier overnight along I-93 south in Salem, reducing traffic to one lane.
That work was related to the $43 million interchange, bridge and ramp project under contract with George R. Cairns & Sons of Windham.
DOT’s advice to drivers: “Motorists should remain alert while traveling through the construction zone and obey all posted signs.”
