full_context: Document 1: Belle Vernon Bridge: The Belle Vernon Bridge, also called the Speers Bridge or Speers/Belle Vernon Bridge, carries Interstate 70 across the Monongahela River from Speers east to Rostraver Township in the state of Pennsylvania. Around 1951 it replaced an earlier low-level bridge, which connected Pennsylvania Route 88 via State Street with Pennsylvania Route 906 at the I-70 east ramps, just to the south of the current bridge.

Document 2: Fort Duquesne Bridge: The Fort Duquesne Bridge is a steel bowstring arch bridge that spans the Allegheny River in Pittsburgh, Pennsylvania. It was colloquially referred to as "The Bridge to Nowhere". It was constructed from 1958-1963 by PennDOT, and opened for traffic October 17, 1969 with its predecessor Manchester Bridge (located closer to the tip of Point State Park) closing that same day (it was demolished in the autumn of 1970). The bridge was given the name "The Bridge to Nowhere" because the main span was finished in 1963, but due to delays in acquiring right of ways for the northern approach ramps, it did not connect on the north side of the Allegheny River. The total cost was budgeted at $5 million in 1962. The lack of approach ramps meant the bridge ended in midair, rendering it useless. The northwestern ramps were completed in 1969, allowing access to Pennsylvania Route 65. The northeastern ramps were completed in 1986, with the construction of the northern section of Interstate 279 (North Shore Expressway) which runs through Downtown Pittsburgh's Golden Triangle and north towards Interstate 79.
