If supported Monday, the city will agree to pay roughly 18 percent of the cost of intersection upgrades at the traffic triangle at Cumberland Mills.

The Westbrook City Council, at a meeting Monday at 7 p.m. at Westbrook High School Room 114, will vote to support the final terms of the $1.7 million project. It has been touted as the best solution to safety concerns at the heavily traveled series of intersections off Main Street.

While federal funds will cover $1.4 million of the project, Westbrook will be expected to cover $317,750.

The proposed plan will add a series of traffic signals at the intersections of Main and Cumberland streets, Cumberland Street and Harnois Avenue, and Harnois and Main streets, allowing safer travel for commuters merging onto Main Street, and supplying additional crosswalks for pedestrians. However, the signals would also slow traffic along Main Street, where commuters are not currently required to stop as they travel through the area.

Project funding was approved a year ago by the Portland Area Comprehensive Transportation System, the region’s transportation planning outlet, after a decade-long process.

The redesign process began in 2004, when Maine Department of Transportation officials looked at a safety project at the intersection of Cumberland Street and Warren Avenue, an intersection that was ranked ninth on the state’s list of most dangerous intersections in 2013.

There has also been one fatality in the traffic triangle, when a woman was hit by a motorist in front of Rite Aid on Main Street.
