United States: Blythe Construction works on the Interstate 77 (North Carolina)
In June, 2014, Blythe Construction started work to convert a bridge on the I-77 into a diverging diamond interchange with traffic in two directions to facilitate easier access to the highway. The construction site is in North Carolina at the Cornelius exit of the I-77.
The project consists of converting the interchange into a diverging diamond at the intersection of West Catawba Avenue and Interstate 77, with two-way traffic. It will entail the reconstruction of 0.6 km of the highway, hydraulic cleaning of a side of the current deck, an excavation, the construction of a 573 m rainwater drainage system, laying 7,540 t of asphalt, raising a 330 m barrier, construction of a parapet stay facade as well as upgrading canals and the existing wastewater drainage system. The works will also include signage and lighting as well as various concrete constructions and the installation of boards with different messages.
The construction will be spread out over 369 days. The major part of the works will take place at night.
