RAIL TRAIL OPEN! Bridge 6 on VT 2B and the Lamoille Valley Rail Trail re-opened to traffic on Saturday June 24th. As the project nears completion this week, crews will be completing the line striping on VT 2B, rail trail reconstruction work and site restoration of the project site and staging area.
Please check back for weekly project updates.
In 2017, the Vermont Agency of Transportation (VTrans) will replace the VT Route 2B Bridge 6 over the Lamoille Valley Rail Trail in the Town of St. Johnsbury. The bridge is less than one half mile west of Route 2B’s eastern intersection with US Route 2.
Built in 1936, the 129-foot steel and concrete bridge is in poor condition. In 2013, VTrans evaluated alternatives to repair or replace the bridge that included permanent closure, an at-grade crossing and full bridge replacement. The engineering study recommended complete replacement of the bridge.
The new bridge will have a 28-foot wide roadway including two 11-foot travel lanes, 3-foot wide shoulders and a combination concrete and steel rail. The existing 129-foot bridge is supported by two tall piers adjacent to the rail trail. It will be replaced by a buried corrugated metal plate, 47-foot arch bridge with mechanically stabilized earth walls with precast concrete finish resembling rock. The walls will be built to adjust well to the expected settlement of the steep slope on both sides of the bridge.
J.P. Sicard, Inc. of Barton has been hired to construct the bridge at a cost of $1.76 million. The work will begin in mid-April 2017 and is scheduled for completion by the end of July.
Accelerated bridge construction methods will shorten the length of time to build the bridge. Closure of both the road (50-day closure) and the rail trail (28-day closure) at the construction zone is planned while the existing bridge is demolished and the new bridge is installed. The 28-day closure of the rail trail is expected to begin in early May.
Separate offsite detours for vehicles and trail users will be marked with signs for use during the closures. The Lamoille Valley Rail Trail detour onto town roads has been designated by the Town of St. Johnsbury.
VTrans will issue weekly project updates throughout construction. The updates will be posted on this website or you can receive the update via email.

VERMONT'S ACCELERATED BRIDGE PROGRAM
Since starting this program in 2012 to expedite project delivery speed using efficient and innovative methods, the Vermont Agency of Transportation has rebuilt 28 bridges.
By reducing the time it takes to construct a new bridge, VTrans has been able to save money spent on design, utility and Right-of-Way impacts and road closures. It also minimizes disruption to travelers and commerce.
The Accelerated Bridge Program encourages early and continued public engagement, streamlining design and plan preparation while exploring innovative contracting and construction techniques.
