EXISTING CULVERT TO BE REPLACED

Jamaica – ER STP 013-2(12)
Project Location: Town of Jamaica in Windham County on VT 100 over an un-named brook. The bridge is located approximately 0.2 miles north of the intersection of VT 30 and VT 100.

The Jamaica VT 100 Bridge 82 project will replace the existing structure with a new concrete box culvert. The existing Jamaica VT 100 Bridge 82 is a 66-inch diameter corrugated metal pipe and carries an unnamed brook under VT 100. The culvert is undersized and needs to be replaced with a properly sized culvert that can accommodate the design stormwater flows. The brook channel was damaged during Tropical Storm Irene and needs to be repaired to prevent channel erosion.
VTrans evaluated alternatives for replacement of the Jamaica VT 100 Bridge 82. Several alternatives were considered including no action, replacing the culvert with various sized culverts and placing the new culvert on a new alignment under VT 100. Given the various factors, including impacts to environmental resource areas, right-of-way and existing utilities, VTrans determined replacing the culvert along the same alignment was the best alternative.
The new culvert/bridge will be a Precast Concrete Box Culvert, which is fabricated off-site and constructed in a short period of time. The new structure will be 63’-0” long, 10’-0” wide and 7’-0” tall. VT 100 will remain the same width and maintain the same alignment. Utility poles will be relocated along the easterly side of VT 100 and guardrail will be replaced along the westerly side of VT 100. Stone rip-rap will be installed on the channel bottoms and embankments to stabilize the channel. The new culvert will be lined with 2’-0” of stone to promote aquatic organism passage.
The bridge will be constructed with Accelerated Bridge Construction (ABC) methods, which will expedite construction and reduce disturbance to the public. There will be an allowable 60-hour road closure, which will allow the existing culvert to be removed, the new culvert installed and VT 100 restored to carry traffic. Single-lane closures should be expected both prior to and following the road closure period.

Target Construction Schedule: Construction activities will take place beginning in June 2015. The allowable bridge closure period is one consecutive 60-hour period between July and August as coordinated with the towns. The contract is scheduled to be completed by November 6, 2015.
