The New Hampshire Department of Transportation announces night work associated with the construction of the four new Exit 5 Interstate 93 bridges in Londonderry.

Weather permitting, work to install portable concrete barrier along Interstate 93 Northbound will take place on the nights of Thursday, May 31 through Friday, June 8, 2012. This work will occur during non-commuter hours, from approximately 9:00 pm to 3:00 am each night. It’s anticipated this work will take a minimum of two nights to complete.

This work will require traffic on Interstate 93 northbound to be reduced to one lane utilizing a high-speed lane closure. The newly constructed barrier will accommodate work to construct median crossovers and drainage in preparation for the next phases of construction on the northbound I-93 lanes and bridges.

Bridge steel erection operations will also take place on the nights of Monday, June 4 through Tuesday, June 5, weather permitting. This bridge work will require traffic on NH Route 28 northbound and southbound to be intermittently detoured utilizing I-93. This bridge work will also require traffic exiting I-93 northbound to NH 28 northbound and I-93 southbound to NH 28 southbound at Exit 5 to be intermittently detoured to reverse direction at the next I-93 exit. This closure will take place during the non-commuter hours of approximately 9:00 pm to 3:00 am on the nights of June 4 and 5. Minor traffic delays can be expected.

This work is part of the construction of four new I-93 Exit 5 bridges, NH Route 28 reconstruction, and I-93 reconstruction in the Exit 5 area. Severino Trucking. Co., Inc. of Candia, New Hampshire is the general contractor for the $37 million project, which is scheduled for completion in June 2014.
