The Bay Bridge is now undergoing its annual inspection, and motorists may encounter lane closings during off-peak hours on weekdays.

The Maryland Transportation Authority says drivers on the bridge might spot equipment such as "Snooper" trucks on the bridge, as well as inspectors climbing on the twin spans. Among other things, inspectors will be looking at the condition of the cables that support the suspension part of the bridge. The inspections will continue through next spring.

If weather permits, the authority will close one lane of the three-lane westbound span next Monday-Thursday for the inspection and for maintenance work. It will close the eastbound span entirely Monday-Thursday from 8 p.m. to 5 a.m. the following mornings and Friday night from 8 p.m. until 7 a.m. Saturday for preservation work. Two-way traffic will  be in effect on the westbound bridge during those periods.
