(July 28, 2015) – The Maryland Department of Transportation’s State Highway Administration (SHA) will close one of two lanes and alternate traffic using a flagging operation on the Thomas Johnson Bridge  (MD 4) on Wednesday, July 29, 2015 beginning at 9 p.m. through 5 a.m. to repair the navigational lights.

This work is weather-dependent and may be rescheduled in the event of rain or high winds. The SHA asks for motorists’ patience during the flagging operation as crews work overnight to complete the work.

While SHA and its partners work hard to maintain safe traffic mobility in work zones, each driver needs to actively modify his or her driving style to help prevent crashes. Stay alert – look for reduced speed limits, narrow driving lanes and highway workers. Slow down and don't follow too closely. Safer Driving. Safer Work Zones. For everyone!
