Road improvements totaling $3.6 million are underway on Eldorado Parkway and Custer Road near the new McKinney H-E-B store.

The construction began in October and includes widening Eldorado Parkway from four to six lanes in the area between Custer Road and Orion Drive, according to Senior Engineer Blake Sills.

There will also be additional turn lanes added, other intersection improvements at the Custer Road-Eldorado Parkway intersection and a new traffic signal associated with the H-E-B construction, Sills said.

H-E-B’s third Dallas-Fort Worth area store, located at the northeast corner of the intersection Eldorado Parkway and Custer Road, is expected to open this summer. A traffic impact analysis estimates that the store will generate an additional 6,500 cars in the area each day, Sills said.

However, improvements at the intersection were planned as part of the city’s Capital Improvement Program prior to the H-E-B development, Sills said. The multimillion-dollar project is funded by the city of McKinney, the McKinney Community Development Corporation, private development and the city of Frisco.

The project also includes widening and repair work on the bridge over Rowlett Creek, a portion of Eldorado Parkway just east of Custer Road. Eastbound traffic along this route closed Feb. 27 and is currently detoured to Stonebridge Drive. The roadway is expected to reopen in late May, Sills said.

Following the reopening of the eastbound side, the westbound side will close, and traffic will also be detoured to Stonebridge Drive. Repairs to the westbound side of the bridge are expected to be completed in mid-July, Sills said.
