context_page_description: Pittsburgh, surrounded by rivers and hills, has a unique transportation infrastructure that includes roads, tunnels, bridges, railroads, inclines, bike paths, and stairways.
context_section_description: Unlike many other major U.S. cities, Pittsburgh lacks a dedicated contiguous beltway surrounding the city. I-76 (Pennsylvania Turnpike), I-79, and I-70 form a roughly triangular-shaped "beltway," but the distance of these roads from the city center and the need to exit and enter each leg in order to continue circling the city render them impractical as a beltway; commuters are forced to use secondary roads to go from suburb to suburb. The Allegheny County Belt System is an attempt at dealing with this without building additional infrastructure. The Pittsburgh Wayfinder System is a similar system that aims to guide travelers to popular destinations and services in the city proper.
