MARION — Drivers can expect work on main roads this summer, according to a conversation on pavement management at a March 16 Selectmen meeting.

Based on an evaluation conducted by BETA Group, Inc, the Department of Public Works determined Water Street, Holmes Street, School Street and Parlowtown Road to be in “the most critical condition of the town” and a top priority for repaving, said Engineering Manager Meghan Davis.

The Public Works Department plans to advertise the project in mid-April and anticipates construction beginning this summer, after a contractor is chosen at the end of May.

Two-way traffic flow will remain open throughout the project, with no summertime backups expected. The selection of adjacent streets — Water and Holmes, and School and Parlowtown — will also fast-track the project, Davis said, by reducing time spent on “multiple re-mobilizations and maneuvering of equipment by the contractor.”

“These sections of roadways really won’t take that long at all,” Davis said, adding that construction should only take a few days.

The project, covering approximately one mile of roadway in total, will cost $141,535.

An additional four miles of roadway, currently in slightly better condition, have also been earmarked for routine maintenance. These minor repairs, including patches and crack seals, will be addressed after the repaving projects are completed.

Marion’s overall pavement condition index rating hovers in the mid-70s — a score indicating that the town’s roads are in “pretty good shape” on average, according to Public Works Department Director David Willett.

“Out of all the other municipalities I’ve worked for my career, I’ve never seen a municipality over 70,” Willett said.

The Board of Selectmen also advised fixes to Spring Street and recommended that the Public Works Department alert the state about potholes and repairs needed on Route 6.

“I’m really excited this is moving ahead,” said Selectmen John Waterman. “This is really good.”
