A 10-mile highway rehabilitation in Warren County, NC to the Virginia state line - Services provided include Transportation Design.

Our team led the engineering design for the rehabilitation of 10 miles of interstate in Warren County to the Virginia state line. The project features unbonded concrete overlay of the existing pavement with upgrades to the roadway profile and superelevation. The design included improvements to substandard typical section criteria and inadequate drainage conditions along the corridor, and realignment of an existing on-ramp to lengthen the acceleration lane and taper. Summit provided all roadway design, design coordination, and project management, and managed subconsultant services for hydraulic/drainage and transportation management plan (TMP) design. Summit staff developed the construction phasing that was carried through TMP design. Additionally, Summit assisted NCDOT in coordinating VDOT approval of plans, and development and approval of contract provisions and the state-to-state agreement.

Engineering design and survey for the City of Roxboro at the intersection of Chub Lake Street and Ridge Road - Services provided include Transportation Design and Surveying.

We provided engineering design and survey services to the City of Roxboro for this LAPP project funded by a Congestion Mitigation and Air Quality (CMAQ) grant through NCDOT. The original intersection of Chub Lake Street with Ridge Road and Crestwood Drive had an offset configuration located at the top of a large crest vertical curve. Limited sight distance, off set turning patterns and limited capacity led to a poorly performing intersection. Left turn congestion, particularly peak hour, was magnifying an inherent safety problem related to the offset configuration. The initial project scope included adding a left turn lane onto Chub Lake Road from Ridge Road, signalization and improved intersection geometrics. However, during right of way acquisition coordination, the city was able to purchase an adjacent parcel in its entirety thus allowing for roadway realignment to eliminate the intersection offset. Summit assisted the city with ROW/easement assessments and platting.
