Concrete Pavement Progress www.acpa.org 8 I-40 CPR Express Design-Build Project, Winston-Salem, NC CONTRACTOR: The Lane Construction Corporation OWNER: North Carolina DOT ENGINEER: Progressive Design Group, Inc. The goal of this project was to improve the cloverleaf interchange of I-40 and US52 to handle expected traffic volume increases from a two-year shutdown of Business 40. The project involved removing and replacing existing damaged jointed concrete slabs and placing new, jointed concrete pavement. Facing a requirement to remove and replace sig- nificant amount of concrete pavement in a single construction season, would have been challenging enough, but The Lane Construction Company also faced many other factors, including: • Managing restrictions that limited lane narrowing or lane closures between 5 am to 7 pm (Monday thru Friday). • Completing undercuts that were required ahead of placing new concrete pavement, all within the same shift during the week or within the same weekend closure. • Encountering continuously reinforced concrete or extra depth concrete that required modification of concrete removal methods. • Contending with reduced work areas and night work. • Managing high-volume, high-speed traffic on both I-40 and US52. • Managing the project around event-related restrictions, which included all holidays, Wake Forest football home games, the 10-day long Dixie Classic Fair restrictions (which extended from 6 am to 9 pm), Bowman Gray Stadium Racing events, and Winston-Salem State football games. • Coordinating with surrounding projects and man- age resources using a non-conventional work schedule. E X C E L L E N C E A W A R D S US 160/US 550 Concrete Pavement Rehabilitation CONTRACTOR: ACME Concrete Paving, Inc. OWNER: Colorado DOT ENGINEER: Colorado DOT, Region 5 Durango Residency The Colorado DOT used a cost-effective strategy to rehabilitate a busy highway, and despite challenges, was able to complete the project ahead of a very busy tourism season. The project involved work on the concrete surface and shoulder on a 27-year-old section of US Highway 160/550 through the City of Durango. The $6 million project had a few challenges, including two change orders that pushed the project completion date out two months. One of the greatest benefits of the project was that it was a more cost-efficient alternative to an estimated $40 million to $60 million that complete reconstruction would have cost. Concrete batching was allowed only during daytime hours because of local ordinanc- es, but ACME Concrete Paving could work day and night for six days per week to complete the work on time. This schedule also allowed the contractor to avoid the local lane closure restriction, which in turn, allowed crews to work large sections with minimal traffic impact. As a result of the efforts of the project team, the business own- ers, residents, and travelers in this area have are now driving on a 27-year-old pavement that has now has an additional 15 to 20 years of life added to it.
