Maryland Route 157 (MD 157) is a state highway in the U.S. state of Maryland. The state highway runs 4.79 miles (7.71 km) from MD 158 in Sparrows Point north to North Point Road in Dundalk. MD 157 is an L-shaped highway serves as the primary highway through Dundalk and from Dundalk to Interstate 695 (I-695). The two highways to which MD 157 is assigned, Merritt Boulevard and Peninsula Expressway, were constructed as a four-lane divided county highway in the early 1960s. In the late 1960s, Merritt Boulevard was extended as ramps to I-695 that also serve MD 151 and MD 150. MD 157 was assigned to the highway in Sparrows Point in the early 1990s and extended through Dundalk to its present northern terminus in the late 1990s.

Route description

MD 157 begins at an intersection with MD 158 (Bethlehem Boulevard) just north of the former Bethlehem Steel complex in Sparrows Point. MD 158 is used to access northbound I-695 (Baltimore Beltway. MD 157 heads north as Peninsula Expressway, a four-lane divided highway that crosses over I-695 and has a half-cloverleaf interchange with southbound I-695 in the direction of the Francis Scott Key Bridge. The state highway veers northwest and reduces to a four-lane undivided highway at Reservoir Road. MD 157 crosses Bear Creek on a drawbridge and expands to a four-lane divided highway that enters Dundalk. The state highway crosses over the CSX rail spur between Baltimore and Sparrows Point before reaching Merritt Boulevard. MD 157 turns northeast onto Merritt Boulevard; the roadway continues straight as Merritt Avenue toward Sollers Point Road. The state highway passes through the Dundalk communities of Stanbrook and Eastfield, through which the highway passes several shopping centers. From the intersection of Holabird Avenue and Wise Avenue north to German Hill Road, the highway has six lanes. After crossing Bread and Cheese Creek, MD 157 reaches its northern terminus at North Point Road. The roadway continues through a partial interchange with MD 151 (North Point Boulevard) and has ramps to and from MD 150 (Eastern Avenue) in the direction of Essex before merging with I-695 in the direction of Essex.^[1][2]

History

The original MD 157 was Chapel Road from MD 462 near Webster to Havre de Grace in Harford County, which was removed from the state highway system in 1956.^[3][4] Meritt Boulevard was constructed as a four-lane divided highway from North Point Road, which was then part of MD 20, to the center of Dundalk in 1960.^[5] Peninsula Expressway was built from the center of Dundalk to Sparrows Point, including a new bridge over Bear Creek, in 1960 and 1961.^[6][7] Like the pre-existing drawbridge to the west that carried Dundalk Avenue over Bear Creek, the Peninsula Expressway bridge carried a toll from its completion through 1977.^[7][8] The Dundalk Avenue bridge was removed around 1985.^[9]

In 1963, the existing road north from the Merritt Boulevard – North Point Road intersection was expanded to a divided highway through its junction with MD 151.^[10] This section of highway was reconstructed in 1968 and 1969 as the ramps between North Point Road and I-695 that also serve MD 151 and MD 150.^[11][12] The portion of Peninsula Expressway south of the Bear Creek bridge was brought into the state highway system as MD 157 around 1991.^[13] When I-695 was transformed from a two-lane viaduct to a four-lane surface freeway between 1995 and 1999, MD 157's interchange with MD 158 was transformed into an interchange with I-695.^[14][15] The remainder of Peninsula Expressway and Merritt Boulevard to North Point Boulevard became part of MD 157 around 1999.^[15][16]
