C. William Hetzer Inc. was awarded the construction contract.
Construction on the first phase is set to begin Wednesday and will involve installing traffic signals and turn lanes and widening the road at the intersections of Robinwood Drive and Medical Campus Road and at Mount Aetna Road and Yale Drive, county Engineering Department Project Manager Steven K. Spalding said.
"Everyone should expect some minor inconveniences over the next couple of months in the way of flag men and the like," Spalding said. "Our preference is to have as little impact as possible on the traveling public."
Weather conditions will determine the time this phase will take but it should be finished by next spring, Assistant County Engineer Joseph Kroboth III said.
In the next phase, Robinwood Drive will be widened into four lanes, from Mount Aetna Road to Medical Campus Road, and a median similar to Halfway Boulevard's will be built, Spalding said.
It is at this stage that major traffic inconveniences can be expected, but the county engineering department will monitor daily traffic flow and complaints from the public and modify the construction plan as needed, Kroboth said.
The work will go on during the summer and be completed in the last week of August, he said.
An extension of Yale Drive, which connects it to Medical Campus Road, was completed in October and will be opened to traffic in the "very near future," Spalding said.
