Community update: Warsaw Road Swing Bridge Temporary One Lane Closures

Trent-Severn Waterway National Historic Site

December 6, 2021, Peterborough, Ontario – Parks Canada would like to advise that Warsaw Road Swing Bridge will be temporarily reduced to one lane for vehicle traffic on Friday December 10 and Saturday December 11, between 9:00 a.m. to 3:30 p.m. for temporary removal of the cyclist steel plates located on the outer edge of both traffic lanes on the main bridge deck. Traffic control will be in place. Please exercise caution, respect working crews and equipment, and obey signage and flag persons in the area.

The Warsaw Road Swing Bridge was closed from October 2020 to August 2021 to undergo a full replacement of the bridge superstructure, repairs to concrete abutments, replacement of mechanical, hydraulic and electrical operating systems, and to bring the bridge up to full highway loading. Part of this work included the installation of perforated cyclist steel plates on the outer edge of both traffic lanes to provide a smooth and safe ride over the bridge for cyclists. Following the reopening of the bridge, it was discovered that noise levels on the bridge were elevated as a result of the plates vibrating on top of the bridge grating when vehicles travel over them. The plates will be removed and will be replaced in the spring with new plates that will allow for installation of fasteners to reduce noise levels. Noise from the bridge will not be fully eliminated but rather reduced to levels similar to what existed prior to construction. Cyclists are advised to exercise caution when crossing the bridge until the new plates are installed.

The Warsaw Road Swing Bridge replacement project is part of the Government of Canada’s Federal Infrastructure Investment program. Parks Canada is leading this important infrastructure work to ensure safe, high-quality experiences for visitors by improving heritage, visitor, waterway, and highway assets located within national historic sites, national parks, and national marine conservation areas, including along the Trent-Severn Waterway National Historic Site. We appreciate your patience while we undertake these important investments into the infrastructure in Peterborough.
