Main Street in Yarmouth will be closed for most of the upcoming weekend while a contractor installs framework for the new deck of the Route 1 bridge that crosses Main Street near the Yarmouth Public Library, town offices and North Yarmouth Academy.

The road will be closed from 4:30 a.m. Saturday until about 7 p.m. Sunday.

“During this time, crews will work around the clock to install framework over Main Street for the new deck of the Route 1 bridge that spans Main Street,” said Maine Department of Transportation spokesman Ted Talbot in a prepared statement. “There will be no pedestrian or motor vehicle access to Main Street directly under the bridge during this weekend.”

Route 1 will remain open during the weekend closure. Drivers will be able to access Route 1 from York or School street.

Talbot said the $4.1 million bridge replacement will still take several more months, with an expected completion date of summer 2019.

Talbot said there is no need to worry about the project’s effect on the popular Yarmouth Clam Festival, scheduled from July 19-23. All construction will be suspended during the festival.

After this weekend’s closure, an 11-foot height limit for vehicles will be in effect on Main Street for the duration of the project.

The new bridge will have a 5-foot-wide paved sidewalk on the east side of Route 1 and a 10-foot multi-use path on its west side. New lighting, railings and illuminated crosswalks will also be installed on the bridge.
