CONSTRUCTION ACTIVITIES:
Cold River Bridges completed the final structural concrete placement on Monday, August 11th, using rapid-setting concrete to join the bridge deck slabs. On Tuesday and Wednesday, crews built up the roadway approaches to the proper grades, and Wilk Paving placed the base course of pavement on Thursday, August 14th. The bridge reopened to traffic this afternoon, with a temporary barrier installed and all remaining construction materials and equipment removed from the roadway. Initially, traffic will travel on the bare concrete deck and approach slabs, with top courses of pavement to be placed in the coming weeks.
Additional construction activities are expected in the weeks after the bridge opens, including placing concrete curbs at the bridge corners; installing permanent bridge rail and guardrail; spray-applying a bridge membrane; placing intermediate and top pavement courses; installing asphaltic plug joints at bridge joints; finalizing centerline, edgeline, and traffic signage; and seeding disturbed soils within the project limits. All post-opening work will be completed using single-lane closures, with traffic controlled by a temporary traffic signal.
TRAFFIC IMPACTS:
Vermont Route 100A is now open through the bridge site in Plymouth and is available for through-traffic between Plymouth Union and Bridgewater Corners. Regional signage will be updated to reflect the reopening. Construction activities will continue for the next several weeks using daily lane closures, with drivers stopped and released by temporary traffic signals. Drivers should use caution through the site, as workers will be in close proximity to the traveled lane and road surfaces will be uneven until final paving is completed.
