MD 313 / MD 404 in Denton
Maryland Route 619 (MD 619) is a state highway in the U.S. state of Maryland. Known as Sixth Street, the state highway runs 1.09 miles (1.75 km) from an intersection with 5th Avenue north to an interchange with MD 313 and MD 404 within the town of Denton in central Caroline County. MD 619 is the old alignment of MD 313 and part of MD 404 through Denton. The state highway was designated south of present MD 404 Business when MD 404 and MD 313 were relocated on the south side of Denton in the early 1970s. MD 619 was extended to its current length when MD 404 and MD 313 were moved to the Denton Bypass in 1987.

MD 619 begins at an intersection with 5th Avenue on the south side of Denton. The state highway heads north on two-lane Sixth Street through a residential area. East of the downtown area, MD 619 meets MD 404 Business, which follows a one-way pair on eastbound Franklin Street and westbound Gay Street. Between the two streets, MD 619 intersects Market Street, which was the original alignment of MD 404 through downtown Denton. The state highway continues north through a mix of residences and businesses, passing Camp Road before reaching its northern terminus at a diamond interchange with the Denton Bypass, which carries MD 404 to the west of the interchange and both MD 404 and MD 313 to the east. The roadway continues north as MD 313 (Greensboro Road).
MD 619 comprises part of the old alignment of MD 313 and MD 404 through Denton. MD 313 followed Fifth Avenue and Sixth Street from south to north, while MD 404 entered the town on Market Street and exited to the south concurrent with MD 313. MD 619 was designated between Fifth Avenue and Franklin Street by 1978 after MD 404 and MD 313 were relocated to a one-way pair, eastbound Franklin Street and westbound Gay Street, through Denton in 1972. MD 619 was extended to its present northern terminus when MD 404 and MD 313 were moved from the streets of Denton to the Denton bypass in 1987.
The entire route is in Denton, Caroline County.
