BRUNSWICK — Bridge replacements in three southern Midcoast towns are among the thousands of upcoming projects included in the Maine Department of Transportation’s three-year work plan released late last month.

The report outlines 2,180 projects totaling about $2.7 billion. The three-year plan estimates MDOT will invest in 100 miles of highway construction and rehabilitation; 893 miles of pavement preservation; 2,175 miles of light capital paving for roads and highways; 222 safety and spot improvements; and 166 bridge projects.

The replacement of the Station 46 bridge on Route 1 in Woolwich is among the priciest projects outlined in the report, with a price tag of $32.5 million.

When the steel bridge, located just north of the Taste of Maine restaurant, was built in 1939, it was expected to last about 75 years. Over 80 years later, the bridge is still structurally sound and carries an average of 19,000 vehicles each day, but needs to be updated to today’s construction standards, said MDOT Project Manager Devan Eaton.

According to MDOT spokesman Paul Merrill, the department plans to advertise the bridge replacement project for bids in September, with construction beginning as soon as late fall of this year. Merrill said the project is anticipated to be finished in 2024.

In nearby Brunswick, the Frank J. Wood Bridge connecting Brunswick and Topsham is slated to be replaced for $21.8 million after significant corrosion was discovered on the 1932 steel truss bridge, which sees about 19,200 cars daily.

Merrill said the department plans to start seeking bids for that bridge replacement in July, but a lawsuit filed against the MDOT and the Federal Highway Administration has slowed that process and driven up the cost. The lawsuit was filed in 2019 by the Friends of the Frank J. Wood Bridge, the Historic Bridge Foundation and the National Trust for Historic Preservation in the United States.

“Litigation has already delayed this project, so continued legal action could push this date out further,” Merrill said. “If it advertises in July, construction could begin as soon as late fall. If that happens, our anticipated completion date would be in 2025.”

Farther south, the I-295 Exit 20/Desert Road interchange overpass and the Exit 22/Mallet Dive interchange overpass in Freeport are due to be replaced after they were deemed structurally deficient.

Built in 1957, the Merrill Road Interchange Bridge, sees 9,408 vehicles per day, and the Mallett Drive interchange carries 16,878, according to data from the DOT.

Freeport is looking to add a 12-foot-wide bicycle and pedestrian path to both bridges in tandem with the upcoming project, a request Freeport residents will need to vote on next month to meet the MDOT’s timeline.

The MDOT agreed to split the cost of a multi-use path added to the two bridges with the town, said Wayne Frankhauser, MDOT bridge program manager, which would’ve cost the town $480,000. However, because Freeport decided on a 12-foot-wide path, taxpayers have to foot the bill for the added two feet, bringing the total to $634,000.

Adam Bliss, Freeport town engineer, said “eight-feet is considered the absolute minimum in terms of multi-use path widths, 10 feet is preferred and 12 feet is ideal,” because it allows two bicyclists to pass in opposite directions.

Merrill said the DOT plans to advertise the two overpass bridges for bid in September with construction beginning as soon as this winter. The anticipated completion date for both bridges is late 2024.

Although some projects have been hindered by lawsuits and municipal add-ons, the MDOT doesn’t anticipate any future construction delays due to COVID-19, Merrill said.

“We did have some construction delays in 2020 due to COVID-19 (delays in getting materials and some labor shortages), and we are working with contractors on a case-by-case basis to avoid similar issues moving forward,” he said.
