In the next phase of the Interstate 89 bridge reconstruction project, VTrans will implement crossover traffic patterns redirecting cars across to the oncoming lane between exits 16 and 17, starting July 15.
The project includes four bridges—Bridge 76 north and southbound over Bay Road, and Bridge 77 north and southbound over Malletts Creek. Plans are to replace the existing deteriorated bridge deck with new updated panels and replace the bridge railings in order to meet today’s safety standards. The introduction of crossover traffic patterns will be used in an effort to alleviate congestion, as it will allow two lanes to remain open at peak commuting hours.
From July 15 through October 16, VTrans will close a single lane between exit 16 and 17 during the weekdays, with two lanes of traffic open during peak hours. The direction of traffic will alternate to accommodate peak hour commutes. This means that in the morning commute, two lanes headed southbound will be open, with one directed over to the other side of the highway. During the evening commute, two lanes headed northbound will be open using the same crossover method.
According to VTrans, there will be instances throughout construction that require a closure of two lanes on I-89 between exits 16 and 17 during off-peak evening hours. This means that only one lane of traffic will be open in each direction.
The bridge work also requires six weekend bridge closures between July 19 and October 6 where one lane of traffic will be open in each direction from Friday 7 p.m. through Monday 6 a.m. All weekend closures are weather dependent and VTrans cautions drivers to remain vigilant, specifically to the posted speed limits while construction lasts.
