State Route 2005 is a major 9.3 mile (15 km) long road, running in a southeast-northwest direction. The western terminus is at Pennsylvania Route 320 in Haverford Township, Pennsylvania. Its eastern terminus is at a Cobbs Creek bridge in Darby, Pennsylvania. Past this bridge is State Route 3023, which continues into Philadelphia. SR 2005 is known as Darby Road in Haverford Township, Lansdowne Avenue from U.S. Route 1 to Darby, and Main Street in Darby.

SR 2005 begins at an intersection between two forks of Darby Road and Sproul Road (Pennsylvania Route 320) in Haverford Township, Pennsylvania. Immediately after its western terminus, the two forks join and proceed almost due east into woodland with some residential development. The area is generally referred to as Bryn Mawr, Pennsylvania due to sharing a common ZIP code (19010) with the community; however, Bryn Mawr's census-designated place (CDP) is located wholly within Lower Merion Township. SR 2005 intersects side street Brennan Drive before crossing Ithan Creek shortly upstream from its mouth at Darby Creek. Carrying 9002 vehicles a day, the bridge is listed as functionally obsolete by the National Bridge Inventory (NBI). In evaluating the structural sufficiency of the bridge, the NBI stated that it is "somewhat better than minimum adequacy to tolerate being left in place as is," estimating the improvement cost to be $99,000.
