SCARBOROUGH — Six companies submitted bids for the project to redesign the Dunstan Corner confluence of Route 1, Pine Point Road, Broadturn Road and Payne Road.
Bids opened Wednesday at the Maine Department of Transportation in Augusta ranged from $2.7 million by Gorham-based R.J. Grondin & Sons to $3.8 million by Buxton-based Dearborn Construction.
Town Planner Dan Bacon said the low bid matches preliminary estimates, with the addition of $300,000 of work on water mains by Portland Water District. Eighty percent of the work will be state and federally funded.
Project details include:
• Extending the southbound left turn lane from Route 1 to Pine Point Road.
• Adding a right hand turn lane from Pine Point Road to Route 1.
•Coordinating and lengthening turn lanes on Broadturn and Pine Point Road at Route 1.
•Rerouting traffic to and from Payne Road and Route 1 on a road built north of the Dunstan Corner School Restaurant.
Bacon said the town will pay 20 percent of the original estimated cost and any overruns. Because details on the purchase of some rights of way are still being finalized by the DOT, the municipal cost has not been determined.
An aerial view of plans for Dunstan Corner construction shows the extension of turn lanes on Route 1 and Pine Point Road and a new access road leading to Payne Road from Route 1 north of the Dunstan Corner Restaurant. Work is expected to begin in late September or early October and must be completed by next June.
