Northampton Street Bridge

Kevin is right, this bridge still exists and still carries traffic with a 3 ton weight limit. Owned by the DRJTBC, rehabilitated in 2002. I'll update the page to reflect this.

The Northampton Street Bridge was not replaced in 2002; it is the same 1896 span. Perhaps it was rehabilitated in 2002?

It was severely damaged in the 1955 Delaware River flood after Hurricane Dianne in August; the center span broke and it was repaired. This 1896 bridge replaced an older covered bridge in the same location.
