Roadway Design

GM2 has provided road and highway design services since its inception. GM2 has experience in the development of intersection geometric improvements and roadway design. Our engineers are familiar with intersection capacity techniques that are used to develop lane arrangements and storage length requirements at signalized intersections, the needs of pedestrians and handicapped individuals, the design requirements for different design vehicles, traffic calming techniques, and drainage requirements. This knowledge results in improvements that are context sensitive, aesthetically pleasing and functional.

GM2's highway design team has made significant strides in overall capabilities over the years and is now poised to provide design services on medium and complex networks with the addition of Mr. Jeffery Keefe, PE, LS, who has exceptional highway design and site design experience.

Road & Highway Experience:

Reconstruction of Rowayton Avenue – Norwalk, CT
This project involved a Preliminary Engineering Study to evaluate four alternate vertical clearance designs and the preliminary design to lower 1200 feet of Rowayton Avenue under four tracks of the Metro North Railroad.

Reconstruction and Lowering of Fairfield Avenue – Bridgeport, CT
This project involved the design for the lowering and widening of approximately 700 feet of Fairfield Avenue, including two intersections with two city streets, drainage and the I-95 off ramp.

Reconstruction of I-95, Exit 56 Southbound Ramps, Leetes Island Road, and other roads – Branford, CT
This project involved preliminary design of over 4000 feet of I-95 ramps, 3000 feet of Leetes Island Road, and 3000 feet of other town roads, complete storm drainage, four intersections, and relocation of utilities. Click here for photos.

Intersection Improvements Routes 80/22 – North Branford, CT
This project involved design of the widening and reconstruction of 2.0 km of Route 80 and Route 22 from two to four lanes, two signalized intersections, complete storm drainage system, relocation of utilities, and multi-stage construction. The project also involved extensive retaining walls to minimize wetland impacts, and utility relocation. Click here for photos.

Widening of Payne Road and Bridges – South Portland, ME
This project consisted of widening two 365-foot-long, multi-span bridges from four to seven lanes over active roadways, 4000 feet of roadway reconstruction and four intersections. Three-stage construction was used to maintain two lanes of traffic in each direction.

Re-alignment of Route 207 – North Franklin, CT
This project involved realignment and construction of 600 meters of two-lane highway, complete drainage system, and utilities.

Reconstruction of Monroe Street – Norwalk, CT
This project involved widening and reconstruction of 800 feet of city street, lowering of profile grade to improve vertical clearance, complete drainage system, and location of utilities. Three-stage construction was required to maintain traffic. Construction cost: $1,200,000.

Route 7 Bypass – Brookfield, CT
Design of 5 km extension of existing freeway section of U.S. Route 7 bypass, including a diamond interchange of three major signalized intersections. Responsible for checking and reviewing horizontal and vertical curve alignment and developed signing, pavement markings, and intersection grading plans. Also responsible for preparing property maps, designing major culvert crossings and checking of storm drainage design.
