The Middlebury Bridge & Rail project, a Vermont Agency of Transportation (VTrans) initiative in collaboration with the town of Middlebury, is nearing completion this summer.

The more than $92 million project replaced two nearly 100year-old bridges that crossed the Vermont Rail Corridor in the center of Middlebury with a tunnel in the summer of 2020. A 360-ft. long tunnel replaced the Main Street (60 ft. long) and Merchants Row (80 ft. long) bridges, which addresses several structural deficiencies.

Hurricane Ida, which dropped more than 6 in. of rain in many parts of Connecticut in early September 2021, caused massive flooding, highway closures and water rescues. It also damaged roadways and a bridge on Route 9 Southbound in Cromwell, which is currently being rehabilitated. see BRIDGE page 4

Work began on the project in September and is on track for completion by May 1, according to CTDOT.

Emergency Work to Repair Damaged Hub Prepares to Bridge in Cromwell to Finish in May Build Long Island Stabilization Package The mayor has said she envisions the island as a mid- to long-term solution to help rid the scourge of addiction that continues to plague the city and its surrounding area.

The work being done on Route 9 Southbound is an emergency job that is progressing well.

Arborio Construction of Cromwell, Conn., is the contractor on the project.

BRIDGE from page 1

Arborio Construction of Cromwell, Conn., is the contractor. An Emergency Declaration project was signed by Connecticut Department of Transportation Commissioner Joseph Giulietti on Sept. 7 in order to stabilize and repair an existing 84-in. asphalt-coated corrugated metal (ACCM) pipe that was found to be structurally compromised following the storm event.

The excessive rainfall from Ida caused a large sinkhole to develop above the 84-in. ACCM pipe that conveys an unnamed brook under the ramp and across Route 372 in Cromwell, according to a CTDOT report. Further investigation found the culvert to be compromised structurally due to the erosion around the pipe.

“The work being done on Route 9 Southbound is an emergency job that is progressing well,” according to a CTDOT. “We began the work because the road was settling due to an underground pipe failure following Hurricane Ida. Rather than shutting down the entire road, we are pipe jacking, which is pushing the pipe through the ground. So far, we’ve been prepping the pipe jacking and working on the access roads to get to the pipes. Next, we will excavate for the earth retaining systems on the inlet and outlet sides, pour concrete

A plan to prepare a stabilization package for the buildings on Boston’s Long Island, where the city continues to one day envision an addiction-recovery campus, is again in the works, with the added hopes of rebuilding a bridge to it this fall.

Sources in Boston Mayor Michelle Wu’s administration told the Herald the second week of March that the amount of cash the city is looking to put toward stopping the deterioration of the already dilapidated buildings on the island is still to be decided.

Located in Boston Harbor, Long Island is 1.75 mi. long and covers a total of 225 acres.

Documents outlining a “master plan,” created during former Mayor Marty Walsh’s term, called for a complete overhaul of the island to the tune of $80 million to stabilize all the buildings there, according to the results of a Herald record request.

Wu administration officials, made available to speak about the plan to the newspaper, said they are not looking at a package that big.

The mayor has said she envisions the island as a mid- to long-term solution to help rid the scourge of addiction that continues to plague the city and its surrounding area.

“During Mayor Wu’s visit to Long Island [in January], the need to immediately stabilize and secure some of the existing public health facilities to prevent further deterioration was evident,” her office said in a statement to the Boston Herald.

“Mayor Wu has authorized [the Public Facilities Department] to develop and pursue a stabilization program for the existing facilities while we engage in our own planning around Long Island and the great potential it has to support Boston’s recovery and supportive housing needs.”

and do the physical pipe jacking on the site. Then we will move to a ground remediation plan, which is pressure grouting any voids under the existing roadway.”

The finalized scope of this project includes the full replacement of the existing 260 linear ft. of the 84-in. ACCM pipe by jacking a new 84-in. reinforced concrete pipe (RCP).

New headwalls and compaction grouting also will be installed.

Work began on the project in September and is on track for completion by May 1, according to CTDOT. The construction equipment being used by Arborio on the project includes a Cat 330B excavator, a Volvo EW170 excavator, a Cat CS-431B vibratory smooth drum roller, an Ingersoll Rand 180, air compressor, a Vermeer E2983 Navigator S3 drilling rig and a Wacker Neuson compactor plate.

Boston Looks to Build Bridge as Part of Island Master Plan ISLAND from page 4

dollar amounts for work on the island depending on whether there is a bridge during construction.

The cheapest near-term options, for “Phase 1” of getting two buildings ready to begin handling patients, include $200 million with a bridge open and no stabilization spending, $238 million with the bridge and some stabilization, or $250 million with no bridge.

That would create up to 124 beds of the 500 visualized in the broader $540-millionplus primary plan, which saw no further action after Walsh was chosen by President Joe Biden in early 2021 to serve as U.S. Secretary of Labor.

Walsh always intended to rebuild the bridge, which his administration considered the only viable option for using the small island as a recovery center.

The bridge construction effort — which Walsh’s administration put at $80 million, though other estimates have placed it higher — would replace the former span that the

city removed in 2014 due to its deterioration.

Although the bridge is in Boston, the only way to drive out to the island is by going through Quincy first. The smaller town has fought the construction plans tooth and nail, dragging Boston into an ongoing court fight.

A Wu administration official told the Herald that the city is “hopeful” that bridge litigation will wrap up soon enough for Boston to begin advertising for the project this fall.

The mayor’s office also mentioned the idea of ferry service in lieu of the bridge, and one of the administration’s officials recently noted “nothing is off the table” on that front.

But the Walsh administration long objected to that idea, saying it was too expensive and would not work for emergency responses to the island. Acting Mayor Kim Janey, who ran the city for much of 2021 between Walsh’s departure and Wu’s swearing in, also floated the idea of ferries at one point and ordered up a review, only to quietly drop the idea a few months later, according to the Boston news source. 

construction manager and general contractor. The contractor was awarded three separate construction contracts over the duration of the project in order to advance critical items and maintain the overall project schedule.

The first contract was Early Work Package One, which was the removal of the existing bridges and replacement with two temporary structures. The second project was Early Work Package Two, which consisted of undergrounding utilities, construction of temporary infrastructure, drilling and blasting a 40-ft. diameter by 40-ft. deep launch shaft to be used for three micro tunneling drives for future drainage infrastructure.

The final construction contract was the main project, which consisted of temporary support of excavation, removal of the temporary bridges, excavation of the rail corridor, installation of the precast tunnels and Uwalls, and then reconstruction of roadways, embankments and landscaping features.

The project is substantially complete and is awaiting completion and acceptance, which is anticipated to occur this spring. The remaining work is focusing on punch list items, such as final seeding, plantings and minimal general clean up.

“The tunnel provides vertical clearance for double-stack rail cars,” according to VTrans. “By lowering the rail bed approximately 4 feet, clearance has increased to 21 feet without impacting the grade of the road and sidewalks above. The tunnel provides improved rail alignment, softening the rail curve to allow better horizontal clearance for trains. The project includes drainage improvements, mitigating the risk of icing problems as well as ponding that occurred historically.”

The two bridges were about 300 ft. apart, with one located on Main Street/VT 30 and the other on Merchants Row. The structures were aging.

“For over 25 years, AOT bridge inspection reports documented ongoing deterioration of both bridges,” said VTrans.

“Concrete cracking, delamination and spalling had degraded all bridge components. Embedded steel reinforcement was rusted and exposed. There was leakage through the deck and full-depth holes on the Merchants Row sidewalk, requiring patching. In the spring of 2017, AOT became increasingly concerned about the deteriorated condition of the sidewalks and concrete that fell onto the railroad tracks. A sudden, unplanned emergency resulted in downtown Middlebury road closures for several months.

“The agency decided to replace both

The third year focused on the mobilization and stockpiling of material, bridge demolition, excavation, tunnel installation and roadways approach reconstructions.

The second project was Early Work Package Two, which consisted of undergrounding utilities, construction of temporary infrastructure, drilling and blasting a 40-ft. diameter by 40-ft. deep launch shaft to be used for three micro tunneling drives for future drainage infrastructure.

bridges with temporary bridges in the summer of 2017, until permanent structures were built,” it added. “Both the Main Street and Merchants Row bridges were demolished and travel was restored within four weeks.

[The] tunnel is a notable engineering and design feat within Vermont. After three years of construction, Middlebury stakeholders celebrated the process.”

VHB is the Lead Engineering Designer for the project, which along with the AOT, balanced community needs and development character, local and regional mobility, construction feasibility “all while keeping the rail line active, except during the closure period,” said VTrans. “Communities along the line depend on rail for deliveries of various commodities.”

The project team, which consisted of the owner, designer, contractor and community liaison, worked out a plan that placed utilities in the Printer’s Alley underground so that they did not interfere with crane opera-

tions for the tunnel construction; acquired right-of-way — temporary and permanent; negotiated with Vermont Rail Systems to secure work windows that enabled construction without interrupting rail service; monitored walls, foundations and windows of nearby historic buildings during activities that produced vibrations, as well as noise levels; found ways to mitigate a 100-year flood level of Otter Creek; ensured a design that considered community character and aesthetics concerns; created a safe working environment for workers, motorists and the community; scheduling a construction sequence to minimize community disruption; and developed a communication and outreach program to identify and respond to community concerns.

Replacing the bridges was considered, but VTrans noted that “the tunnel offers better safety, drainage and aesthetics. For example, it adds green space and connects Middlebury Village Green and Middlebury village his-

toric district. Trains can now pass through town with less noise. The tunnel option was supported by the Middlebury select Board as it responds to the 2012 town plan to ‘close up the chasm that exists in the downtown area.’”

Prior to construction, the AOT conducted an environmental assessment in accordance with the National Environmental Policy Act. The project received broad support at public meetings and was endorsed by the Middlebury town select board.

The tunnel changes the town landscape by overlaying the depressed, walled rail bed with green space that links Triangle Park with the Village Green in the heart of downtown.

Aside from the 2017 Early Work Package One, which was the emergency replacement of the existing bridges and the 2019 summer road closures, the traffic plan is based on temporary road and lane closures where work is occurring.

The first permanent infrastructure work began in summer of 2018 with the first year focusing on micro tunneling, access roads and overhead utilities relocations. The second year focused on water, storm and sanitary utility locations and temporary support of excavation and preparatory excavation.

The third year focused on the mobilization and stockpiling of material, bridge demolition, excavation, tunnel installation and roadways approach reconstructions. In 2021, activities focused on landscaping in Triangle Park, Village Green, and Lazarus Park and the reconstruction of Printer’s Alley and final paving.

Last year’s construction activities had crews installing new north and south cap walls, constructing berms and drainage swales along the southwest limits of the train tracks, reconstruction of Lazarus Park and Printer’s Alley, landscaping and hardscaping in Triangle and Lazarus Parks.

Work was suspended during the winter months for between 2018 and 2019 (winter work did occur during the 2019-2020 winter season). During the summer of 2020, Main Street and Merchants Row were closed to traffic.

“Alignment of SOE was critical as we experienced some tight areas in terms of setting precast between lagging/sheet pile walls,” said Bob Hyatt, Kubricky Construction’s senior construction manager.

“No conflicts were experienced, but it was close. Working through the COVID-19 pandemic with zero cases of infection throughout the tunnel construction was a challenge in addition to speaking very highly of the diligence of our personnel to remain safe and infection-free during shutdown. see MIDDLEBURY page 12
