Dunlap's Creek Bridge

It was designed by Richard Delafield and built by the United States Army Corps of Engineers.

It is located in the Brownsville Commercial Historic District and supports Market Street, the local main thoroughfare.

Due to the steep sides of the Monongahela River valley, there is only room for two short streets parallel to the river's shore and graded mild enough to be comfortable to walk before the terrain rises too steeply for business traffic.

[5] This bridge is constructed using five parallel tubular ribs, each made of 9 elliptical segments to form the 80 feet (24 m) arch.

Market Street's lowest stretch runs north of the ramp off the West Brownsville bridge for 3-4 blocks (about the scene here), whereafter it begins a steady climb to the end of the re-routed U.S. Route 40 bridge built at a much higher elevation near the site of the original settlement, the Tavern, Trading Post, and Inn near today's Bowman's Castle .
