Motorists should expect at least another 10 days of delays on a portion of Bob Billings Parkway that is under construction.

Lisa Patterson, a city spokeswoman, said construction crews would keep traffic restricted to one lane in each direction on a portion of Bob Billings Parkway between Kasold Drive and Monterey Way.

Patterson said a sanitary sewer project near Lake Alvamar required crews to work inside manholes on Bob Billings Parkway.

Work has been going on in the area since early this month, Patterson said.
