Maryland Route 151
Encyclopedia
Maryland Route 151 is a state highway
in the U.S. state of Maryland
. Known for most of its length as North Point Boulevard, the state highway runs 10.8 miles (17.4 km) from 7th Street in Sparrows Point north to U.S. Route 1
(US 1) in Baltimore. MD 151 is a four- to six-lane divided highway that connects the communities of Edgemere
and Dundalk
on the Patapsco River Neck of southeastern Baltimore County
with industrial areas in Sparrows Point and East Baltimore. MD 151 was originally constructed in the early 1920s from Sparrows Point to Edgemere. The highway was connected to Baltimore by the Baltimore County portion of MD 20
, a number also assigned to the highway from Rock Hall
to Chestertown
in Kent County
. During World War II, MD 151 was extended north through Dundalk on a new divided highway parallel to MD 20 and through East Baltimore on an expanded Erdman Avenue to connect the Bethlehem Steel
complex at Sparrows Point with MD 150
and US 40
. In the late 1960s and early 1970s, Interstate 695
(I-695) was constructed parallel to MD 151 through Dundalk.
. Sparrows Point Boulevard continues south to a gate south of F Street. MD 151 heads northeast as a four-lane divided highway. The state highway leaves the steel complex by crossing over the Patapsco & Back Rivers Railroad and Wharf Road, which is MD 151B and with which MD 151 has a modified trumpet interchange. At Sparrows Point Road, MD 151's name changes to North Point Boulevard and the highway curves north to bypass Edgemere. The state highway intersects MD 158
(Bethlehem Boulevard), which heads east toward North Point Road. North Point Road heads south through Edgemere toward North Point State Park
and Fort Howard
. Just north of MD 158, MD 151 has a partial interchange with I-695 (Baltimore Beltway), which includes a ramp from MD 151 to northbound I-695 and a loop ramp from southbound I-695 to MD 151. The movements to and from the Francis Scott Key Bridge
are made via MD 158 to the west.
MD 151 passes under a rail line owned by Norfolk Southern Railway
and intersects Wise Avenue before passing through the North Point Village
neighborhood of Dundalk, where the highway is paralleled by North Point Road on the east. At Cove Road, a connector to the parallel I-695, North Point Road switches to the west side of MD 151. The area north of North Point Village, where Patapsco River Neck narrows to a width of 1 miles (1.6 km) between the Back River
and Bear Creek, was the site of the Battle of North Point
, a September 12, 1814 engagement that was part of the encompassing Battle of Baltimore
in the War of 1812
. At Bread and Cheese Creek
, northbound MD 151 crosses to the east side of I-695, which runs in the median of the state highway. Northbound MD 151 and northbound I-695 and the southbound directions of each highway are connected to each other by ramps. Northbound MD 151 crosses over I-695 and has a U-turn ramp before the highway's partial interchange with the ramps between I-695 and the northern end of MD 157
(Merritt Boulevard). There is no access from northbound MD 151 to MD 157. The state highway continues northwest along the southern edge of the Eastpoint Mall
ahead of its cloverleaf interchange with MD 150 (Eastern Avenue), then enters an industrial area where the highway intersects the Canton Railroad
at grade.
MD 151 enters the city of Baltimore just west of its intersection with Rolling Mill Road and Kane Street. The state highway passes under I-95, a Norfolk Southern Railway railyard, and the Amtrak Northeast Corridor. At North Point Road, MD 151's name changes to Erdman Avenue and the highway veers west to pass under CSX
's Philadelphia Subdivision. The state highway veers northwest at its crossing of I-895 (Harbor Tunnel Thruway) just before the highway's cloverleaf interchange with US 40 (Pulaski Highway), which also includes a ramp from southbound MD 151 to southbound I-895. Connections between eastbound US 40 and northbound MD 151 are made via Mapleton Avenue just east of I-895. MD 151 continues northwest concurrent
with US 40 Truck as a six-lane boulevard between the Armistead Gardens
neighborhood to the east and industrial facilities on the west. The state highway passes by Archbishop Curley High School
and through the Belair-Edison
neighborhood before reaching its northern terminus at US 1 (Belair Road), onto which US 40 Truck turns west. Erdman Avenue continues northwest as a two-lane street along the eastern edge of Clifton Park
to MD 147
(Harford Road).
to recommend MD 151 and MD 20 from Sparrows Point to Baltimore be expanded from 20 to 40 ft (6.1 to 12.2 m) in width.
Modern MD 151 was constructed between 1940 and 1944 as a defense access project to better connect Baltimore with Bethlehem Steel's steel mills and shipyards at Sparrows Point. MD 151 was reconstructed and extended north as a four-lane divided highway from Sparrows Point to Wise Avenue in Dundalk between 1940 and 1942. This construction included the highway's bypass of Edgemere; the bypassed portion of Sparrows Point Road from the expanded highway east to MD 20 was designated MD 718 by 1946. In Baltimore, Erdman Avenue was expanded to a divided highway from US 1 to US 40 and extended south to North Point Road by 1942; MD 151's underpasses of the Baltimore and Ohio Railroad
(now CSX) and Pennsylvania Railroad
(now Amtrak) and its interchange with US 40 were completed at that time. MD 151 from Wise Avenue to the Baltimore City line was constructed between 1942 and 1944; this work included the cloverleaf interchange with MD 150.
With the construction of modern MD 151, MD 20 was split into several disjoint segments of North Point Road: one from near Fort Howard to MD 151 in Edgemere, another along the northbound side of MD 151 from Edgemere to North Point Village, a third on the southbound side MD 151 from North Point Village to the MD 150–MD 151 interchange, and a fourth between MD 151 and US 40 in Baltimore. The Baltimore City segment was removed from the state highway system in 1956. The portion of MD 20 from near Fort Howard to MD 718 in Edgemere was transferred to county maintenance in 1987. The remaining portions of MD 20 and MD 718 in Edgemere were removed from the state highway system around 1999.
MD 151's interchanges with Wharf Road in Sparrows Point and with MD 20 and Bethlehem Boulevard in Edgemere were built by 1963. The state highway's partial interchange with Merritt Boulevard was constructed in 1969 and the crossover interchange with I-695 was built in 1971. I-695 was completed between Merritt Boulevard and MD 151 in Edgemere in 1974. In 1999, as part of the reconstruction of I-695 from the Key Bridge to Edgemere from a two-lane viaduct to a four-lane surface freeway, MD 151's interchange with MD 20 and MD 158 in Edgemere was reduced to a standard intersection and the highway's present partial interchange with I-695 was built.

History
MD 151 was originally assigned only to Sparrows Point Road, which was improved as a concrete road from the southern end of the highway at the Bethlehem Steel complex to North Point Road in Edgemere by 1921. North Point Road was also built as a concrete road from Edgemere to the North Point community in Dundalk by 1921. That highway, which was designated MD 20 in 1927, was extended south toward Fort Howard and north from North Point to US 40 in Baltimore in 1923. By 1934, heavy traffic between Baltimore and Sparrows Point led the Maryland State Roads CommissionMaryland State Highway Administration

to recommend MD 151 and MD 20 from Sparrows Point to Baltimore be expanded from 20 to 40 ft (6.1 to 12.2 m) in width.
Modern MD 151 was constructed between 1940 and 1944 as a defense access project to better connect Baltimore with Bethlehem Steel's steel mills and shipyards at Sparrows Point. MD 151 was reconstructed and extended north as a four-lane divided highway from Sparrows Point to Wise Avenue in Dundalk between 1940 and 1942. This construction included the highway's bypass of Edgemere; the bypassed portion of Sparrows Point Road from the expanded highway east to MD 20 was designated MD 718 by 1946. In Baltimore, Erdman Avenue was expanded to a divided highway from US 1 to US 40 and extended south to North Point Road by 1942; MD 151's underpasses of the Baltimore and Ohio Railroad

(now Amtrak) and its interchange with US 40 were completed at that time. MD 151 from Wise Avenue to the Baltimore City line was constructed between 1942 and 1944; this work included the cloverleaf interchange with MD 150.
With the construction of modern MD 151, MD 20 was split into several disjoint segments of North Point Road: one from near Fort Howard to MD 151 in Edgemere, another along the northbound side of MD 151 from Edgemere to North Point Village, a third on the southbound side MD 151 from North Point Village to the MD 150–MD 151 interchange, and a fourth between MD 151 and US 40 in Baltimore. The Baltimore City segment was removed from the state highway system in 1956. The portion of MD 20 from near Fort Howard to MD 718 in Edgemere was transferred to county maintenance in 1987. The remaining portions of MD 20 and MD 718 in Edgemere were removed from the state highway system around 1999.
MD 151's interchanges with Wharf Road in Sparrows Point and with MD 20 and Bethlehem Boulevard in Edgemere were built by 1963. The state highway's partial interchange with Merritt Boulevard was constructed in 1969 and the crossover interchange with I-695 was built in 1971. I-695 was completed between Merritt Boulevard and MD 151 in Edgemere in 1974. In 1999, as part of the reconstruction of I-695 from the Key Bridge to Edgemere from a two-lane viaduct to a four-lane surface freeway, MD 151's interchange with MD 20 and MD 158 in Edgemere was reduced to a standard intersection and the highway's present partial interchange with I-695 was built.
