Reconstruction and rehabilitation of an approximately 2-mile section of Stephenson Highway from 14 Mile Road to Interstate 75 in Troy is under way. Stephenson Highway is a four-lane divided road. The project is a joint venture between Six-S Inc., of Waterford Township and C & G Myers Construction LLC, of Milford.
The existing concrete pavement had deteriorated to a point where maintenance was no longer cost-effective. The city of Troy has had concrete slab replacement work done on Stephenson Highway over the past two years in preparation for this project. The remaining concrete slabs are being removed and replaced. They are being used as a base course for a new asphalt pavement overlay.
Concrete curb and gutter is also being placed along the west side of the southbound lanes to further enhance the area. Several existing crossovers are being relocated to improve the safety of the road. A new traffic signal will be constructed at the intersection of Stephenson Highway and Maple Road with modifications to existing signals north and south of the intersection. Existing pedestrian crossing locations will be upgraded with new sidewalk ramps and push buttons. Traffic is being maintained on one lane of Stephenson Highway throughout the duration of the project.
Wally Hamdan, project manager for the joint venture, explained that work was done on the inside lanes and crossovers first, and then work proceeded on the outside lanes. All of the paving will be done when the other work is completed. He explained that doing it this way provides a better quality road. "This way we can get a better finish," Hamdan said. He added that doing it this way also provides greater efficiency.
"This provides for less mobilization. We decided to finish the inside lanes, including landscaping, so that we don't have to go back to it and do touchup work later. When we're done with the outside lanes, we'll be done with the entire project," Hamdan said.
The approximately $3.5-million project includes milling and repairing joints. Approximately 10 inches of non-reinforced concrete is being placed and overlaid with 3 inches of asphalt.
The project includes the placement of 9,427 tons of 4E3 hot mix asphalt (HMA); approximately 7,000 tons of 5E3 HMA; 319 tons of HMA approach; 18,500 square yards of 10-inch concrete; approximately 20,000 feet of curb; 32,600 square yards of 21AA aggregate base; and 20,000 feet of silt fence for erosion control. Pavement removal amounts to approximately 20,000 square yards, and excavation totals approximately 13,500 cubic yards. Milling on the project totals approximately 20,000 square yards. The project began in March and it will be completed in October.
Six-S and C & G are doing the excavation, preparation, removals, stone, grading, and concrete paving. Six-S and C & G are performing approximately 75 percent of the work.
Subcontractors on the project include GM & Sons, of Whitmore Lake (miscellaneous concrete); Cadillac Asphalt; and Metrosweep Environmental Services, of Waterford Township (landscaping).
