Existed | 1967[20]–present |
Tourist routes | Journey Through Hallowed Ground Byway |
U.S. Route 15 Business (US 15 Business) is a business route of US 15 through Emmitsburg. Known as Seton Avenue, the highway runs 2.34 miles (3.77 km) between junctions with US 15 on the south and north sides of the town.[21] US 15 Business follows the original alignment of US 15 through Emmitsburg. The highway serves the St. Joseph's College and Mother Seton Shrine campuses, which are home to several emergency management institutions and a shrine dedicated to Elizabeth Ann Seton, the first person born in the United States to be canonized by the Roman Catholic Church. The U.S. Highway's bypass of the town was constructed between 1963 and 1965.[20][22] US 15 Business was assigned to the old alignment of US 15 from south of Emmitsburg to the Pennsylvania state line by 1967.[20] The business route became unsigned by 1989 and was truncated at its present northern end by 1999.[23][24]
US 15 Business begins at a superstreet intersection with US 15 (Catoctin Mountain Highway) opposite county-maintained Old Frederick Road. Access to northbound US 15 requires following southbound US 15 to a median U-turn. The superstreet intersection replaced a standard highway junction in 2004.[25] US 15 Business heads north as a two-lane road that immediately intersects the old alignment of US 15, Old Emmitsburg Road, and crosses Toms Creek. The business route passes the campuses of St. Joseph's College and the Mother Seton Shrine. St. Joseph's College is a defunct liberal arts college for women whose operations were absorbed by Mount St. Mary's University. The campus is now the National Emergency Training Center, a Federal Emergency Management Agency facility that is home of the National Fire Academy, United States Fire Administration, Emergency Management Institute, and the National Fallen Firefighters Memorial. The Seton Shrine comprises the Basilica of the National Shrine of St. Elizabeth Ann Seton and St. Joseph's Provincial House of the Daughters of Charity of Saint Vincent de Paul.[21][26]
US 15 Business continues north into the Emmitsburg Historic District, where the highway intersects MD 140 (Main Street) and passes St. Euphemia's School and Sisters' House. The business route veers northeast and crosses Flat Run before approaching its northern terminus at US 15. Traffic from northbound US 15 Business to northbound US 15 is required to follow the ramp to southbound US 15 and turn around at US 15's interchange with MD 140. US 15 Business continues north to North Seton Avenue, a service road that parallels the southbound direction of US 15 toward the Pennsylvania state line. That intersection is connected to a one-way southbound ramp from US 15's intersection with Welty Road. The intersection was changed to remove access from northbound US 15 Business to northbound US 15 in 2007.[27] East of US 15, Welty Road immediately intersects Old Gettysburg Road, the old alignment of US 15 north towards Gettysburg.[21][26]
Gettysburg business loop
Location | Gettysburg, Pennsylvania |
---|---|
Length | 14 mi (23 km) |
Tourist routes | Journey Through Hallowed Ground Byway |
U.S. Route 15 Business (US 15 Business) is a surface road in Adams County, Pennsylvania that serves as a through street in the Gettysburg area. It marks the original incarnation of US 15, before a freeway bypass was created.
The southernmost portion of the business loop is lightly traveled, serving as a rolling connecting route between the more utilized portions of this highway and a similar business loop in Emmitsburg, Maryland. The road's designation officially begins at the Pennsylvania–Maryland state line in Freedom Township. South of Gettysburg National Military Park, the road is narrow and features infrequent development, while at its southern edges, a small number tourist facilities appear. Traffic picks up greatly during peak travel months through the park, which uses this highway as one of two main access ways. At the northern border of the greenspace, the route becomes Gettysburg's main street, featuring many stoplights and often cars parked on both sides of the street. North of the city center near Gettysburg College, large homes line the street. The highway then turns northeast, passing as an overly narrow route past commercial development, before traveling into sparsely populated farm county. In unincorporated Shrivers Corner, the route meets up with Pennsylvania Route 394, with which it is cosigned for its final one-half mile, as it passes into a US 15 freeway juncture.
Major intersections
The entire route is in Adams County.
