OK..what's the best way around this?


Route 100 in Plymouth to close for a month
Beginning Aug. 30, Route 100 in Plymouth will be closed for a month, with the possibility of an extended closure. Crews will replace two bridges and culverts. A detour around the construction adds over 7 miles to the through-trip and goes over 100A, which will also be under construction for the entirety of the bridge projects, reducing traffic at times to a single lane. At the moment, there is no truck detour, so all vehicles will be forced to deal with 100A’s steep passages.

The Aug. 30-Sept. 26 timeline is tentative; a final announcement will be made two weeks prior to the planned closure, according to VTrans. If bedrock is found during construction on bridge 114, Route 100 may stay closed for an additional three weeks.

The closure will take place during some of peak leaf peeping season. And the detour will likely back up traffic.

Public Information Consultant Shawna Kitzman stated that VTrans views both the 100 and 100A construction as a single project.

VTrans estimates that the combined cost of replacing the 50-year-old bridges, 114 and 115, as well as the corresponding culverts, will be about $1.8 million. Willey Earthmoving Corp. of Windsor will handle the construction. The culverts, which channel the flow of Reservoir Brook, do not meet hydraulic standards and fall into the categories of “serious” and “poor” conditions. Although not noted by VTrans, travelers from the south could take Route 103 to Route 4, arriving in Killington by way of Rutland. While longer in distance, this route involves larger roads that permit higher speeds.

Well that sucks

One option for all you snowbirds coming up 91 (not mentioned in the article), you could take Exit 7 >VT Route 11> VT Route 106 > to US Route 4 in Woodstock . . .

That adds about 15 minutes, so you'd have to compare that to the time for the 100A single lane option.

That should hurt the ticket revenues from the cop in Plymouth.

Probably a good potential for waiting longer than 15 minutes in the construction zones . . .

Poor Sherriff will have to go on a diet, no revenue with a closed road!

[Seacoaster]

Any idea exactly where it will be, in other words, will we be able to get to the boat launch at Woodard from RT 4 side of 100?

[Mister Moose]

There' an excavator and a construction trailer parked just uphill or just south of the gravel pit, and before Woodward coming from the North.

Reservoir Brook leads out of Woodward Reservoir and follows along Rt 100 until it joins the Ottauquechee behind the Cedar Brook. Reservoir Brook crosses back and forth across Rt 100 a couple times on the way. Two of those crossings are deficient and need reconstruction to comply with current day standards.

Location is in the immediate vicinity of the gravel pit.

PLYMOUTH BRIDGE BR#114
BF 013-3(17) Plymouth
Replacement of existing culvert along with related approach roadway and channel work, BR114 on VT100 over Reservoir Brook.

Project Location: Town of Plymouth in Windsor County on Vermont Route 100 over Reservoir Brook. Culvert 114 is located approximately 1.7 miles south of the intersection of VT Route 100 and US Route 4 in Bridgewater, VT.

Background: The Plymouth Culvert 114 project includes the replacement of the existing corrugated galvanized metal plate pipe culvert. The existing culvert was installed in 1971, and is 66 feet in length. The structure has a clear span of 7 feet. The structure currently has a rating of 3, “serious”, with deterioration in the form of large perforations throughout the entire length of the structure. It was also determined that the structure does not meet hydraulic standards.

Engineering Study: VTrans evaluated alternatives for the rehabilitation or replacement of the culvert in an engineering study completed in March, 2020. This study assessed the proposed design criteria for the structure, right-of-way, rare/threatened/endangered species impacts, hydraulics, archeological resources, and wetland impacts. Several alternatives were considered, including: no action, rehabilitation, and replacement with a bridge or buried structure. Complete replacement alternatives were considered for different traffic maintenance options: short term road closure with detour, temporary bridge, or phased construction with traffic maintained.

Recommendation: Based on the age of the structure, site constraints, and current conditions, the engineering study recommended replacement of the culvert with a precast concrete box, with traffic maintained on an official signed detour. The closure duration will be approximately 7 days, during which time the detour will add 7.2 miles to the thru route. There is no local bypass route. If bedrock is found during boring operations, the closure duration will be extended to 3 weeks. Update: Project will be contracted with Bridge 115 with a 28 day closure period to include both bridges.

Roadway: The existing roadway meets most of the geometric provisions of the Vermont State Standards. The only known roadway deficiency in the project area is the lane and shoulder widths for the approach and bridge lanes. This is not a high crash location, therefore no changes to the approach lanes are proposed. However, the replacement will include building out the lane and shoulder widths over the structure, to accommodate any future increase of approach roadway width.
Detour Route: Traffic will be rerouted from the south side of the project site south on VT Route 100 to VT Route 100A. Traffic will continue the length of VT Route 100A, turn left on US Route 4, travel 5.6 miles and turn left on VT Route 100 back to the north end of the project site.

PLYMOUTH BRIDGE BR#115
BF 013-3(13) Plymouth
REMOVE AND REPLACE EXISTING CULVERT WITH A NEW METAL ARCH, BR115 ON VT100 IN PLYMOUTH, OVER RESERVOIR BROOK.

Project Location: Town of Plymouth in Windsor County on Vermont Route 100 over Reservoir Brook. Culvert 115 is located approximately 1.4 miles south of the intersection of VT Route 100 and US Route 4 in Bridgewater, VT, at approximately mile marker 9.34.

Background: The Plymouth Culvert 115 project includes the replacement of the existing corrugated steel multi-plate pipe culvert. The existing culvert was installed in 1971, and is 80 feet in length. The structure has a clear span of 8 feet, providing a waterway area of approximately 64 square feet. The structure currently has a rating of 4, “poor”, with deterioration in the form of large perforations throughout the entire length of the structure. It was also determined that the structure does not meet hydraulic standards.

Engineering Study: VTrans evaluated alternatives for the rehabilitation or replacement of the culvert in an engineering study completed in March, 2017. This study assessed the proposed design criteria for the structure, right-of-way, rare/threatened/endangered species impacts, hydraulics, archeological resources, and wetland impacts. Several alternatives were considered, including: no action, rehabilitation, and replacement with a bridge or buried structure. Complete replacement alternatives were considered for different traffic maintenance options: short term road closure with detour, temporary bridge, or phased construction with traffic maintained.

Recommendation: Based on the age of the structure, site constraints, and current conditions, the engineering study recommended replacement of the culvert with an open bottom buried structure: concrete arch or combination structure of metal arch with concrete pedestals. It is suggested that traffic be maintained on an official signed detour. Closure duration will be approximately 3 weeks, during which time the detour will add 7.2 miles to the thru route. There is no local bypass route. Update: Project will be contracted with Bridge 114 with a 28 day closure period to include both bridges.

Roadway: The existing roadway meets most of the geometric provisions of the Vermont State Standards. The only known roadway deficiency in the project area is the lane and shoulder widths for the approach and bridge lanes. This is not a high crash location, therefore no changes to the approach lanes are proposed.

It will be closed just north of Woodward Reservoir.

[RustyK]

Any idea when 100 is going to re open? Getting tired of 100A

Also Rt 12 bridge off of exit 9 of 91 is closed for construction too...

[throbster]

It's supposed to open today. That detour sucks. I got stuck behind a tour bus on 100A and of course I was running late to get home.

[Skivt2]

I heard it will be three more weeks.
