This Accelerated Bridge Construction project includes the replacement of four bridge decks on Vermont I-89 between exits 16 and 17 in the town of Colchester. The 7 ½” concrete decks on Bridges 76N and 76S over Bay Road and Bridges 77N and 77S over Mallet’s Creek will be replaced with 8 ½” precast Deck Panels. TL-5 Concrete barrier and new expansion joints will also be installed as part of this project. Due to high traffic volumes during commuting hours, restrictions are in place for lane reductions. Two-way traffic will need to be maintained between the hours of 6:00 am and 9:00 am for the southbound traffic and 3:00 pm and 6:00 pm for the northbound traffic during the week. The contractor will have access to the bridges during non-peak hours with an anticipated closure of one weekend for each bridge to complete the work. Crossovers will be used to maintain traffic during demolition and replacement of each bridge deck.
Construction is anticipated to begin in the late summer or early fall of 2019. During this period the contractor will be constructing cross overs and a construction access in Mallet’s Creek. The bridge decks will be removed the following spring starting in April and will be completed Prior to July 2020.
