Shelburne Road Reconstruction

J.A.McDonald,Inc. performed the reconstruction of US Route 7, "Shelburne Road", while maintaining two traffic at all times, for 35,000 vehicles daily, over a two mile stretch of Vermont's busiest highway corridor. The timely success of this project was centered around the successful design and implementation of a highly functional Traffic Control Plan. Local residents and media heralded the success of the traffic control plan and the rate at which progress was achieved throughout the duration of this multi-year project.

The project entailed a "Total Reconstruction and Widening" of US Route 7. All new underground utilities were installed, to include, water, sewer, underdrain piping, storm drainage, sewer manholes, stormwater catch basins, electrical vaults, etc. One of the major installations on this project involved the installation of a 10ft x 16ft precast concrete box culvert section, to carry an unnamed tributary beneath Shelburne Road. This highly skilled installation had to be performed in phases, complete with steel sheeting driven to support traffic, while adjacent sections of the new structure where placed.Coordination of this installation, within the confines of the established traffic control plan, was just one more of the many challenges experienced through out the construction of this project.

Once all underground utilities were installed a mass excavation was initiated that removed all the existing subbase materials to a depth of five feet below newly designed finish grades. At some locations, this mass excavation required mass excavation of soild rock, with required drilling and blasting within a highly confined and restricted area. The rock excavation was excavated and processed through J.A.McDonald's specialized crushing and processing equipment to produce subbase material that was incorporated into the new roadway as new subbase material. J.A.McDonald's crushing/processing equipment and personnel were able to produce products that met contract specifications via processing the on-site rock excavation vs having to import this material from offsite commercial sources.

Upon completion of the mas excavations, and the replacement of new subbase materials, new curb and sidewalks were installed. Two new signal systems were installed, complete with loop detectors imbedded into the final layer of bituminous pavement. New street trees were planted and all greenbelt areas were loamed, with a special modified topsoil mix, and seeded.

The Shelburne Road Project was a very high profile project, that was completed ahead of schedule, within budget, and showcases the highly skilled capabilities of J.A.McDonald, Inc.

St. Johnsbury, VT - Westside Infrastucture

The St. Johnsbury, VT - Westside Infrastructure Project - consists of the reconstruction of 1.5 miles of roadway to include new sewer mains and services, new water mains and services, as well as a new storm drainage system. The total linear footage of new pipework to be installed exceeds 36,000 LF.

One of the many challenges of this project involves the installation of a Temporary Water System to maintain service to approximately 125 residential and commercial entities while the old water mains are removed and new water mains installed. Like wise temporary by-pass pumping will be utilized to maintain sewer and stormwater flows during the replacement of sewer and stormwater systems.

Upon completion of the new water, sewer, storm systems, the 1.5 miles of roadway will be reconstructed including installation of stabilization fabric, subbase gravels, pavement and pavement markings. 11,200 linear feet of granite curbing and 40,000 sf of concrete sidewalk will be installed prior to the restoration of lawns, drives and all associated work items.

This project is currently ahead of schedule with an anticipated completion date scheduled for September 2014.

Waterbury, VT - Roundabout

The US 2/ VT 100 Roundabout is located at the intersection of US Route 2 and the VT route 100 adjacent to Exit 10 on I-89.

The Roundabout's intent is to improve traffic flow at this intersection and create a positive and welcoming first impression at Waterbury's northern gateway. Additional objectives include providing safe and efficient crossings for pedestrians, improving and reducing conflict for access to adjacent businesses, and accommodating large trucks servicing Waterbury's businesses.
