Road construction is under way along Interstate 70 in Sherman and Thomas counties.

Traffic will not be affected during the first phase of the work, but the shoulders might close adjacent to where the contractors are working during daylight hours.

The project begins at the junction of I-70 and Highway 253 and extends east approximately to the Sherman/Thomas county line -- 8 miles in length.

The roadway phase of the construction will begin in the spring and will include daily lane closures of I-70. During that point, I-70 traffic will be switched to single lane, two-directional traffic.

APAC-Kansas Inc., Hays division, is the prime contractor in charge of the $7 million project.

The construction is expected to be completed by July, according to the Kansas Department of Transportation.
