Description: The New Hampshire Department of Transportation partnered with McFarland Johnson on New Hampshire’s first use of Slide-in Bridge Construction (SIBC), also known as the lateral slide method. Completed in the fall of 2020, the project successfully replaced two bridges over and adjacent to the Bearcamp River on NH Route 16 in Ossipee. The SIBC (lateral slide) method provided an innovative solution to the key challenges at the project site, including extensive natural resources, proximity to businesses, and a locally and regionally critical route that carries an average of 11,000 vehicles per day. This presentation will touch on factors that were considered in the Department’s decision to select the SIBC method, and the design and construction of key bridge elements as well as lessons learned.
