NHDOT-Ossipee 14749 Slide-In Bridge Construction

The New Hampshire Department of Transportation (NHDOT) recently partnered with McFarland Johnson (MJ) on the successful completion of New Hampshire’s first project to utilize Slide-in Bridge Construction (SIBC) methods. SIBC, a type of Accelerated Bridge Construction, was used to expedite the replacement of two bridges over and adjacent to the Bearcamp River on NH Route 16 in Ossipee, New Hampshire. The existing bridges consisted of four-span (168 feet in length) and five-span (392 feet in length) steel girder structures on steel bent piers.
