LEWISTON – A section of Webster Street in Lewiston, a stretch of Route 117 in Norway and three bridges that cross the Androscoggin River are in dire need of repair.

Nearly one-third of the major roads in Maine are in poor or mediocre condition, according to a report released this week.

A $2.2 billion funding shortfall over the next nine years will leave the state unable to move ahead with many critical highway and bridge improvement projects, according to the report by TRIP, a national nonprofit transportation research group based in Washington, D.C.

The report includes a list of the 25 most deteriorated sections of roadway in the state. Among the worst five:

• A section of Webster Street in Lewiston, east of Pond Road, extending northwest to Route 126;

• A stretch of Route 117 in Norway, northeast of Otisfield Gore Road, extending north to Route 118.

The other three are in Dexter, Hampden and Wells.

Among the report’s five most deficient bridges are three over the Androscoggin River: on Route 219 between Turner and Leeds, on Route 201 in Brunswick and on North Main Street in Peru.

“TRIP’s report confirms what is no surprise to the citizens and businesses of Maine,” Dana Connors, president of the Maine State Chamber of Commerce, said in a prepared statement.

“In order to move Maine forward, we must make investment in our roads and bridges a higher priority,” said Connors, who also is a former Maine transportation commissioner.

He noted that a $113 million transportation bond issue will be before Maine voters on Tuesday, June 12.

The bond would cover highways and bridges, airports, public transit facilities, ferry and port facilities including port and harbor structures and statewide bicycle and pedestrian trails. Approval would make the state eligible for $244 million in federal matching funds.

Frank Moretti, a spokesman for TRIP, said Wednesday that the release of the report was timed to the bond vote.

“We advocate for efficient and safe highways and we time studies to when critical decisions are to be made,” Moretti said. “But we don’t take positions on legislation or bond issues.”

He said the study was conducted a few months ago by looking at data and surveying transportation agencies.

One of those agencies, the Maine Department of Transportation, says it needs $5.4 billion for road and bridge improvements from 2007 to 2016, but it expects highway funding to be only $3.2 billion for those years.

More money is needed if the state wants to significantly improve road and bridge conditions, make safety improvements, address traffic congestion and enhance economic development opportunities, according to the report.

Part of the problem is that over the past three years, the average cost of materials used for highway construction, including asphalt, concrete, steel, lumber and diesel, have increased by 33 percent.

Increases in population and travel have placed additional stresses on Maine roads, resulting in congestion on key urban and summer travel routes. Vehicle travel in Maine increased 26 percent from 1990 to 2005, and is expected to increase by another 25 percent by 2020.

Route 26 through Oxford, Norway and Paris is listed among the most congested roads. Others are I-295 in South Portland, Route 1 near Belfast and Searsport, and Route 1 near Wiscasset and Edgecomb.

Highlights of the “Future Mobility in Maine” report:

• 32 percent of major roads in Maine are in poor or mediocre condition.

• Bad roads cost Maine motorists an average of $285 a year – a total of $286 million. Costs include vehicle depreciation, repairs, increased fuel consumption and increased tire wear.

• A desirable goal is to have 75 percent of major roads in good condition. Only 48 percent of Maine’s major roads are in good condition.

• About one-third of Maine bridges show significant deterioration or do not meet current design standards. Forty-nine percent are 50 or more years old. Most bridges are designed to last 50 years before requiring significant repairs.
