The Bennington By-Pass Project

The Bennington By-Pass Project, known as VT Route 279, is the Route 7, North/South, and Route 9, East/West, by-pass of downtown Bennington VT. There were four projects that comprised the northeast quadrant of this by-pass. J.A.McDonald, Inc. constructed two of the four projects, known as the Bennington AC NH 091-1(53) and (54) projects.

The Bennington (53) project was completed August 15, 2010, at a contract value of $21,779.60 and the Bennington (54) was completed August 15, 2012 at a contract value of 18,095.40.

The work performed on these projects included major earth and rock excavation, drainage, subbase and pavement, construction of two new bridges and rehabilitation of three other bridges.

The (53) project included a 470 ft. multi-span bridge over Furnace Brook and a 253 ft muti-span bridge on East Road over VT Rte 279. The Furnace Brook Bridge had a center pier that was 90ft high from the bottom of the footing to top of the pier cap. The structural steel for this bridge was curved and had a web height in excess of 9ft, making this steel the deepest webbed steel currently utilized on any bridge structure in the State of Vermont.
Major items of Work Performed:
Earth Excavation = 565,000cy; Solid Rock Excavation = 185,250cy; Sub base Materials = 66,820cy; Drainage and Utility Installations = 19,632 lf; Concrete = 4070cy; Reinforcing Steel = 703,707 lbs; Structural Steel = 2,316,483 lbs.

The (54) Project consisted of reconstructing the northerly clover-leaf intersection of Vt. Rte. 279. This project consisted of On-Ramps, Off-Ramps , and Slip-Ramps. The Ramps are alphabetized from 'A' to 'R', yes there were a total of 18 Ramps on this project. Maintaining Traffic with a well implemented Traffic Control Plan was peri-mount. Three bridges were also rehabilitated, complete with painting of structural steel.
Project Highlights:
  • JAM presented a Value Engineering proposal for solid rock excavation at the Exit 2 location that was accepted by VTrans - this VE proposal represented a 20% cost savings on the solid rock excavation item.
  • JAM presented a VE proposal for the reinforced earth wall at abutment #!, of the Furnace Brook Bridge that was accepted by VTrans. This represented a 10% cost savings on the construction of abutment #1.
  • JAM achieved substantial completion one year in advance of final completion on the (53) project.
  • In recognition of its achievements on the (53) project, JAM was awarded the "2009 AGC of VT Best Builders Award For Outstanding Quality of Work and Effort" - New Construction

US Rte. 7 New Relocation Manchester VT

The largest clear span corrugated, galvanized, metal plate structure east of the Mississippi River measures 42 feet and o­ne and o­ne-half inches across, which is a large half circle. The Manchester "Super 7" Project had eight main structures including three bridges, four box culverts, o­ne arch structure; all major projects of their own. This project needed maximum expertise to complete. Dynamic Compaction, a unique process of increasing density to specified areas underlying embankments, was used in some areas o­n this project.

Moving 1.2 million cubic yards of excavation along with removal of 200,000 cubic yards of rock and erection of 700,000 pounds of structural steel bring quality workmanship to the reckoning point. Again J.A. McDonald, Inc. built success.

Sunderland, VT. Tropical Storm Irene Roadway Rehabilitation in the Green Mtn. National Forest

On August 28, 2011, Tropical Storm Irene dumped a mass amount of rain over parts of Vermont. Many roadways sustained massive wash-outs and the Kelly Stand Roadway, in the Green Mt. National Forest, Sunderland VT sustained sever damage to 8.94 miles of roadway. Portions of the damaged roadway, were repaired by the Town of Sunderland, but a section of the roadway has not been repaired and remains closed to traffic.

The Kelly Stand Road is the only east-west route through the mountains between VT Route 11/30 in Manchester and VT Route 9 in Bennington. It connects US -7 in Sunderland - Arlington to VT Route 100 in Stratton-Wardsboro providing recreational access to the trail-head parking area for the Appalachian Trail/Long Trail and snowmobile access to the VAST north-south Corridor 7 trail in the winter months.

Major items of work included within the scope of this project include rebuilding of roadway, rebuilding of one bridge and the repair of a second bridge to include the installation of two cofferdams, placement of approximately 30,000cy of heavy rip-rap on roadway banks, bridge and culvert locations. There is an additional 60,000cy of excavation and select materials associated with this project.

In addition to the rebuilding of the roadway and drainage structures, substantial re-building of the stream channel will be performed, along with removal of in-stream debris.

On-site rock will be drilled, blasted and processed via on-site crushing, to manufacturer the multiple rock products required for the completion of this project.

Bristol Bridge Replacement

This project is located on Route 116 in Bristol Vt. The project consists of constructing a new bridge, over the New Haven River, and associated roadway approaches.

This challenging project consists of the complete removal of existing bridge #7, complete removal of existing bride #8, and the construction of a new, 368ft. two span bridge on an improved alignment. A two-way temporary bridge and detour will be constructed to maintain traffic while the existing structures are being removed and the new structure being constructed.

Some of the major items involved in the scope of work for this project included the installation of three temporary cofferdams, along with the driving of 9400lf of HP 14x89 steel piling. This bridge project will consume in excess of 1700cy of concrete, containing 273,000 lbs. of reinforcing steel. The bridge surface will be supported by 617,000 lbs. of structural steel, spanning 368 feet, from abutment #1, to a center pier, to abutment #2.

This project is a multiple year project with completion of the project in June 2015.

New Public and Private access roads will be built as part of the project as well as realignment of TH-25. 

US Rte 7 Reconstruction South Burlington VT

The 50,000 vehicles per day make the Southern Connector Project the center of J.A.McDonald, Inc.'s capabilities and reputation. Constructing the new interchange of Route-7 and I-189 was an eight phase, two-year project. First, half of a million cubic yards of excavation were moved, then finished with 30,000 tons of pavement. Equipment, knowledgeable workforce and experience make a project of this size achievable. The commitment involved Sundays and nights because success with minimum disruption was the goal to be achieved.

This project again, was a J.A. McDonald, Inc. success heralded by local media, town and state personnel. The project included, from start to completion, all peripheral needs: sidewalks, bike path, utilities, traffic light, landscaping, and a major seven lane, two-span bridge - a job well done. The Southern Connector not o­nly reduced the heavy traffic burden substantially but also allowed for minimal disruption. These factors make this two-year Southern Connector project a valued o­ne for reference of J.A. McDonald, Inc.

South Burlington, Georgia Design Build

The Project consists of replacement of six Culverts at three locations on I-89 in the towns of South Burlington and Georgia VT. The Georgia culvert replacement will be done by the Sequential Excavation Method (tunneling).

The Project is a Design-Build whereas the Contractor and the Design team combine to one entity. The purpose is to deliver to the Vermont Agency of Transportation (VTrans) a quality project with a long life span. 

The existing culverts are Corrugated Metal Pipe (CMP) in poor to serious condition, with failure inevitable in the near future. The Design-Build team plan to replace these culverts with Precast Concrete Structures of varying configurations.    

Other Projects

Montpelier, VT. I-89 
Exit 8 Safety Project

The scope of this project is one that JAM Inc. has performed several times over the years. This project is located at exit 8 of I-89, Montpelier VT. The project consists of clearing and grubbing, solid rock excavation, machine scaling, hand scaling, traffic control and other highway related items of work.

The majority of the work to be performed is located at the exit 8 northbound , on ramp of I-89, located in Montpelier, VT. The exit 8 ramps contain existing ledge excavation slopes that have become unstable. This project will remove ledge to stabilize the slopes and achieve proper safety distances from the edge of pavement to the solid rock excavated slope. The 20,000cy of excavated material will be salvaged to the VTrans District Highway Dept. for use on future projects.

Lincoln Bridge Project was a Vermont State AOT project. The Project was part of the states Accelerated Bridge Construction Project (ABC). The project details were to remove the 128' super-structure, demolish and remove the pier, and replace with cast in place footings, precast abutments, precast box beams and a 5" deck overlay. 

The challenge was the cast in place footings needing to marry up with the splice sleeve coupler's that were formed into the precast abutment. The 50 day window allowed for no room for error. 

The project was complete on time and opened to local traffic before school started in the fall.

The Lunenburgh
Project

The Lunenburgh project consists of removing an existing culvert that carries the flow of Hudson Brook under Rt. 2. J.A. McDonald Inc will install a bypass culvert to handle the flow while construction of a new 110'L X20'W precast concrete arch is installed. The project requires traffic control phasing to allow the new arch to be installed. Traffic will be reduced to a one way alternating traffic pattern. 

 Upon completion of the precast concrete arch, J.A. McDonald Inc will rebuild 1000 ft of Rt 2 full depth. 

 The project started in mid April and was completed by September 30, 2016
