Drivers should expect detours around Market Street Bridge for over a year as the bridge undergoes rehabilitation.
On Monday, Market Street Bridge closed to vehicle traffic and is expected to remain closed for 14 months.
The work is part of a $149 million PennDot project that includes reconstruction of the bridge, and other construction work in the area.
Construction work on the bridge began in March 2025, and is expected to be completed by April 2029. The project requires moving around and installing water, electric, gas, and fiber-optic utility lines in the area, The Inquirer has previously reported.
During the bridge closure, cars and bicycles will be detoured to Chestnut and Walnut Streets, according to . The agency has said one sidewalk to pedestrians to cross the bridge during construction.

Six SEPTA bus routes will be detoured in the area for roughly a year starting Monday: buses 31, 44, 49, 124, 125, L1 Owl.
Parking restrictions are also in effect in the area through 2028 because of the project, PennDot spokesperson Helen Reinbrecht confirmed. Those restrictions impact Chestnut Street between 23rd and 22nd Streets, 23rd Street between Market and Walnut Streets, and Walnut Street between 23rd and 33rd Streets.
PennDot work in the area has recently led to temporary closures and detours near Amtrak’s 30th Street Station.
PennDot’s multimillion dollar project is mostly funded with federal dollars, with 20% of the cost paid for by the state.
