Construction is set to begin Monday, May 30 on a 2.8-mile section of Route 4 in Sanford and Alfred.
Crews will be removing a layer of pavement, then will be repaving over the existing road in order to extend the life of the pavement. During construction, traffic will be restricted to one lane of alternating, one-way traffic.
If the project proceeds as planned and there are no weather-related delays, construction should be completed by the end of June.
Pike Industries is the contractor for the $474,000 contract.
