RIDGE ROAD INTERSECTION IMPROVEMENTS

Roxboro, NC

Ridge Rd/Chub Lake St Intersection in Roxboro, North Carolina where our Transportation Design team provided engineering services to improve the intersection.

Project Description
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.

A mini roundabout in the City of Durham at the intersection of Carver Street and Broad Street/Kenan Road - Services provided include Transportation Design.

Our team served as Prime consultant for a Mini Roundabout for NCDOT through the Statewide On-Call Planning and Design contracts. The goal of this project was to improve the operational safety of the intersection of Carver St. and Broad St./Kenan Road in Durham, NC. Due to several rear-end collisions and numerous near-misses, a mini-roundabout was utilized to calm traffic while continuously processing traffic through the intersection, thus eliminating the need for side street traffic to compete for limited gaps in the predominant Carver Street movement. The mini-roundabout approach limited the amount of impact to surrounding property owners but accommodates the turning movement of larger vehicles (transit/school buses, fire truck, etc.) through the use of a mountable center island. The Summit team provided roadway design, hydraulic design, erosion control design, traffic management and pavement marking design, and utility coordination/design services for the project. Summit also participated in NCDOT’s Public Involvement efforts and provided supplemental route location surveys and easement staking as needed to complete the project.

Roadway design, hydrologic/hydraulic analysis, drainage design, TMP/PMP design, utility coordination and design for an NCDOT Design-Build in Divisions 6 and 7 - Services provided include Transportation Design, Surveying, Geotechnical Engineering and Project Management.

As lead engineer, our team is providing roadway design, hydrologic/hydraulic analysis, drainage design, TMP/PMP design, utility coordination and design, surveying, geotechnical engineering and project management for 28 bridges and 26 culverts. Summit is also managing subconsultant services for structure design, hydraulic analysis/ design, utility coordination and ROW acquisition.

A collection of urban greenways along the historic Eno River - Services provided include Construction Engineering and Inspection, Transportation Design, Geotechnical Engineering, Construction Management, Surveying, Land Development, Architecture and Construction Materials Testing and Special Inspections.

Summit was the prime consultant on the Town of Hillsborough’s Riverwalk, a recently-opened collection of urban greenways along the historic Eno River. To develop the initial greenway routing and bridge crossing locations, Summit and its team performed site assessments, detailed surveys, flood plain analysis, historical and archaeological assessment, and agency coordination to gain concurrence on the preferred route. Under supplemental contracts, Summit provided detailed engineering design including greenway trail design, hydraulic design, CLOMR/LOMR, and structure design to develop full construction plans, prepare bid packages, and administer the public bid processes for the resulting two construction projects. During construction, Summit also provided daily inspection and testing services and construction management of the project to final completion. Summit’s ingenuity to utilize a top down construction method saved the town $30,000, shortened construction time by three months, and preserved mature, native trees.
