Project Alert: I-91 Bridge Deck Replacements

Bridges 21N and 21S span the Saxtons River and Saxtons River Road (VT 121) and are located approximately 2.4 miles north of Exit 5 along I-91.

These bridges were built in 1963 and consist of span cast-in-place decks on rolled steel beams. This project will replace the existing decks and repair the piers and pier caps. The bridge decks will be completely removed and replaced. Deteriorated and loose concrete on the piers will be removed and repaired. The bridges will be reconstructed in several phases using crossovers, which transition both directions of traffic on to one bridge.

Saxtons River Road (VT Route 121) traffic will be reduced to one lane using flaggers, as needed, during specific construction activities. Traffic signals may be used for longer duration lane closures under the bridges.

PROJECTED COMPLETION: Fall 2024
