Traffic in and around Laurel Md is not that bad. During morning and evening rush hours the busiest roads in the city are Seventh Street and Route 198 (Talbott Ave). Seventh Street connects Route 198 to both Prince Georges County Laurel and Howard County Laurel. Route 198 also connects to Interstate 95 and the Baltimore Washington Parkway.
Baltimore Ave (Route 1) does get busy during rush hour, but keeps moving. Interstate 95 connects Baltimore and the Washington D.C. Beltway. It seems to be heavier in the morning rush hour than the evening rush hour.
However, from personal experience, the Baltimore Washington Parkway (BW Parkway) seems to have the slowest moving traffic……all the time. The BW Parkway connects D.C. with Baltimore Md and has only two lanes in either direction.
