WORCESTER - The Massachusetts Department of Transportation has awarded the contract for the remake of Kelley Square to J.H. Lynch & Sons.

The Rhode Island-based company was the low bidder for the project at $14.68 million, according to Highway Administrator Jonathan L. Gulliver. Bids were opened last week.

Construction is scheduled to begin next month and the project is expected to be substantially completed by March 2021, in time for the planned opening of Polar Park.

The Kelley Square redesign project is being done in conjunction with the $240 million redevelopment of the area. It includes the construction of a minor league baseball park that will have a capacity of about 10,000 and become the new home of the Boston Red Sox’ Triple A minor league affiliate in April 2021.

The project is intended to reconfigure a high-crash intersection — long considered to be one of the most dangerous and worst traffic intersections in the state — with a hybrid roundabout that features a traffic "peanut" in the center and rerouting various one-way streets in the neighborhood.

It will also feature Worcester's first dedicated bike lane, according to MassDOT.

The peanut-shaped roundabout will send traffic counter-clockwise around Kelley Square. Traffic flow on Millbury Street and Harding Street south of the square will reverse direction to accommodate flow into the roundabout, and a shared multi-use path for pedestrians and bicyclists will loop around the perimeter of the peanut.

Pedestrian crossings will be shortened. Other accommodations include a separated bike path along the north side of Harding Street entering the square, and the extension of the multi-use path down Madison Street to the railroad bridge.

MassDOT is undertaking the Kelley Square project, which is being paid for with state and federal funds.

Earlier this year, the city initiated land-takings for the project. That included 59 temporary and 33 permanent easements over property owned by abutters that the city needed to secure a clear right-of-way for the redesign of Kelley Square.

Many of the easements were small, ranging from 2 square feet up to less than 100 square feet.

Among the biggest takings are 115 Madison St., 8,983 square feet, owned by Madison WG Holdings LLC; 185 Madison St., 8,756 square feet, owned by J&K Gas Inc.; 10 Millbury St., 2,202 square feet, owned by Y Thi Tran; and property at the intersection of Washington and Madison streets, 2,094 square feet, owned by Vargo & Associates aka Vargo & Associates Environmental Consulting Corp.; Madison Street Realty LLC and Kelley Square LLC.

The total cost of the temporary and permanent easements is $1.011 million. It was the city's responsibility to acquire the rights-of-way.
