The Greater Portland Metro is expanding into Scarborough.

The new route will provide service centered along the Route 1 corridor seven days a week, reducing traffic congestion and expanding transportation options in southern Maine, officials said.

The specific stops are still in the works and will be determined based on public feedback, existing and upcoming housing developments and underserved areas.

“We’re thrilled to see transit expanding into new areas of the region,” said Kristina Egan, the executive director of the Greater Portland Council of Governments. “This new service aligns with our long-term vision to make public transportation easier to use with more frequent connections for riders.”

To support this project, the Maine Turnpike Authority has apportioned $3.5 million to be rolled out over five years. Already, the Metro project was awarded $1.3 million in Federal Transit Administration funding by the Portland Area Comprehensive Transportation System. The town of Scarborough has also agreed to commit local funding.

As Scarborough’s population continues to grow, residents have expressed concerns about an influx of traffic and congestion.

The town of Scarborough recently completed a town-wide transportation study for the first time in nearly two decades, guided by the goals to expand transportation networks; prioritize safety in new and updated infrastructure; meet transportation demands in line with population growth; and encourage town connectivity.

“We have an eye toward improving traffic flow and safety,” Town Manager Tom Hall said. “Expanded public transportation is a critical component of our vision for Scarborough’s traffic and transportation goals.”

The next steps involve public involvement, including a survey available at gpmetro.org/scarborough.
