For the first time the City of Philadelphia and PennDOT have installed shared lane markings or sharrows on major bicycle routes in Philadelphia. Sharrows are generally installed when there is not enough width for bike lanes but are installed to remind motorist to share the road with cyclists as well advising cyclists on the most ideal lane position (outside the 4 foot wide door zone).
The first corridor where the City's Streets Department installed sharrows is along Umbria, Main St and Ridge Avenue between Manayunk and the Wissahickon. Additionally, PennDOT installed sharrows on Ridge from the Wissahickon Creek to Kelly Drive in East Falls resulting in nearly 2 miles of markings. Look for sharrows (and a few new bike lanes) on several streets in the next few weeks.
