KITTERY, Maine — Construction crews working on the Sarah Mildred Long Bridge replacement project are expecting to work through the night three days next week.

The increase in activity is because of the placement of concrete for the lift tower pier that is rising out of the Piscataqua River on the Kittery side of the project. The bridge is being built alongside the old Sarah Long bridge, which connects Portsmouth and Kittery along the Route 1 Bypass.

Cianbro, the general contractor on the bridge project, said three placements are scheduled to take place Aug. 8-12. Each placement is in excess of 1,000 cubic yards of concrete and will take up to 16 hours to complete.

The concrete is scheduled to begin arriving by truck at 6 p.m. Monday and will entail approximately 100 truckloads on the first night, with completion expected between 8 and 9 a.m. Tuesday morning. The procedure will be repeated on Wednesday and Friday.

While the operation is not expected to affect traffic significantly, the public can expect increased noise and increased light during the evening hours of operation. Construction trucks are expected to arrive in Kittery via Route 236.

After the concrete placement work is completed in Kittery, construction activities on site will return to normal for three to four weeks, before the concrete placement operation is repeated on the Portsmouth side of the project.

The old Sarah Long Bridge is expected to close Nov. 1, and the new bridge is expected to open by Sept. 1, 2017.
