cTdot CTfastrak contract 1

New Britain, CT

AI provided construction engineering and inspection for Contract 1 of the CTfastrak project. CTfastrak, the first of its kind in CT, is a 9.4-mile-long roadway or guideway, dedicated solely to bus transportation. It provides a public transportation alternative to central Connecticut commuters by circumventing traffic on the heavily traveled I-84 corridor. Contract 1 ran approximately 0.5 mile and included the construction of the first section of the guideway.

This section extended from Main Street to Stanley Street in downtown New Britain, CT. The guideway began at Main Street and included construction of the New Britain Passenger Station, the largest of the CTfastrak stations on Main Street adjacent to Columbus Boulevard. Major structural components of this project included the demolition of an abandoned railroad bridge, over 40 years old, and the construction of a new 635 ft., 5-span bridge carrying the new guideway, and a 12-foot-wide multi-use trail over a heavily traveled Route 9. Modifications to the Route 72 exit ramp, the Route 9 entrance ramp, and Route 71 (Truman Overpass) were made to accommodate vehicular movement to and around the new station. Contract 1 also includes five (5) retaining walls. The project abutted existing main roads and highways, and required staging and maintenance of heavy traffic on all sides.

The construction of the busway under the existing Route 71 overpass required careful protection of the existing foundations including temporary shoring with tie-backs as well as a permanent retaining wall with ground anchors installed between the existing structure’s own piles. This station also features a 400-foot-long, six-bay, arched canopy that has over 100 photovoltaic solar panels to help power the new transit station as well as provide excess power back to the grid. Innovative level curbing for articulated buses and platforms provide easier and faster boarding for all passengers. The station is equipped with smart ticket technology and pre-pay ticket vending machines as well as GPS tracking allowing riders to see accurate, real-time, bus arrival times.
