One Harrisburg bridge will reopen as another is set to close, as part of work on I-83.

PennDOT announced on Wednesday that the 29^th Street Bridge has reopened following a complete reconstruction, days before the 19^th Street Bridge is due to close for an estimated year-long rebuild.

Both bridges are part of the I-83 Capital Beltway Project, East Shore Section 3, which includes adding lanes to the highway, replacing bridges, and other work.

The 29^th Street Bridge closed last July and was then demolished and replaced. PennDOT will now undertake a similar process at the 19^th Street Bridge, which will close on the night of Oct. 26. The closure will extend from Paxton Street to Greenwood Street, and includes the ramp from northbound I-83 to 19^th Street. The ramp from 19^th Street to northbound I-83 closed in August and will remain closed until work is complete.

PennDOT will have long-term detours in place, which can be found on their website.

The 19^th Street Bridge is slated to reopen in October 2026, with the ramps expected to reopen in spring 2027.

The updated 29^th Street Bridge is a three-span structure that includes two 11-foot travel lanes, sidewalks and a shared use lane for bikes and pedestrians protected by a concrete barrier.
