Contractors have started working on a $29.5 million, two-year project that will connect Route 100 in Howard and Anne Arundel counties.
Only a small segment of Route 100 is in Howard county between Interstate 95 and U.S. 1. The new project is a three-mile section that will connect with the Baltimore-Washington Parkway.
The I-95 to Baltimore-Washington Parkway segment will include five new bridges. Two bridges will carry U.S. 1 and relocated Race Road over Route 100, two others will carry Route 100 over Deep Run stream and the CSX-MARC railway, and one bridge will take relocated Race Road over Deep Run.
The project, awarded to the Williams Construction Co. of Baltimore, is expected to be finished by winter 1994. It began in mid-September with work on sediment control, traffic signs and the establishment of a field office.
Construction will require periodic single lane closures along U.S. 1, Route 176 and Route 100, except during the peak hours of 6 to 9 a.m. and 3 to 7 p.m.
State highway officials say traffic along Route 176 has become an increasing problem with the development of business and industrial parks along the road.
