Summit 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.
