Pennsylvania drawbridge map — the Schuylkill spans

Philadelphia keeps Pennsylvania’s movable bridges — the Passyunk Avenue and University Avenue drawspans over the Schuylkill still open with a couple hours’ notice, a working leftover of the river’s industrial era. Tap any bridge for its federal opening rule.

How it works: opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117). Pennsylvania publishes no live drawbridge status, so schedules are the tool here. Bridges without a map pin are listed with their rule but haven’t been precisely located yet. Also see Seattle and the other state pages on the Maps hub.
