PARIS – The skies above the Oxford County Regional Airport in Oxford will be quieter for about three weeks this spring as work proceeds on the runway.

The work at the airport will focus on the rehabilitation of a single 3,000-foot runway, as well as runway and taxiway lights, earthwork, tree clearing and sign relocation.

Last year, the county received a $1,873,400 grant from the Federal Aviation Administration toward the project. The county and state will each match 2.5 percent of the cost, while the FAA grant will cover the remaining 95 percent.

In February, Glen Builders Inc. of North Conway, N.H., was awarded the project for $1,493,023.

Representatives from the county, Glen Builders, the engineering consulting firm Hoyle, Tanner and Associates, and Oxford Aviation, a company that rents space at the airport, met on Wednesday morning to discuss the project.

Woody Wilson, construction project manager with Hoyle, Tanner and Associates, said the work will be completed within 45 days. Construction on the runway is expected to begin May 19 and go for 21 days.

Wilson said the construction schedule will aim to have minimal effect on the operations of Oxford Aviation, an aircraft refurbishing company.

“We’re working around their schedule of maintenance for aircraft that are coming in and out,” Wilson said.

Glen Builders must also agree to pay damages in the amount of $1,200 for every day the project exceeds the 45-day limit and $2,000 for every day the runway work exceeds the 21-day limit.

During the construction, barricades and other markers will be put up at the airport to prevent planes from landing or taxiing on the runway. A notice to airmen will also be put out advising pilots of the work.

The airport does not have an air traffic control tower or weather equipment. During the 21 days of runway work, the rotating beacon will be shut down. While the runway will go back into operation after that period, night operations will be suspended until the new lighting is installed.

According to a permit issued by the Department of Environmental Protection, tree clearing in wetlands near the airport must be done in frozen conditions. Wilson said this may necessitate the return of the company later in the year to finish the project.

Glen Builders’ projects in western Maine include the Magic Lantern Theater in Bridgton, the replacement of Severance Lodge in Lovell, and condominium units at Shawnee Peak in Bridgton and the Bethel Inn.
