Highways & Bridges Team Experience

Parrish & Partners’ professional personnel have been involved in all phases of highway and bridge projects and programs of various sizes and complexities. Representative individual experience of key team members prior to joining Parrish & Partners includes:

  • Interstate 73 Phase 1 (Interstate 95 to US 501), Dillon, SC: The finalized interstate project will connect Michigan to South Carolina via the Interstate 73 (I-73) corridor. I-73 Phase 1 consisted of ten bridges within 5.7 miles from I-95 to US 501 in Dillon County, including a multi-level interchange and other supporting structures. Responsibilities included leading final design of the ten bridge structures.

California Ave 1 I585

  • I-585 Rehabilitation and Bridge Replacement, Spartanburg County, SC: This 2-mile $14 million interstate rehabilitation project included interchange jacking and overpass replacement (California Avenue) in downtown Spartanburg. During the design phase of this project, the overpass at California Avenue was struck by a tractor trailer and subsequently closed. In an effort to improve traffic flow in and around the City of Spartanburg the design phase was expedited so that the project could be let 6 months ahead of schedule. As Engineer of Record, responsibilities included project management, multi-discipline design oversight, QA/QC, utility coordination, and public involvement while with SCDOT.
  • US 378 over Little Pee Dee River and Swamp, Horry and Marion Counties, SC: This project consisted of seven bridges over the Little Pee Dee (LPD) Swamps and one bridge over the LPD River. The bridges over the swamps ranged from 200 feet to 440 feet, with the LPD River Bridge stretching 1,034 feet with eight spans. Each bridge site contained multiple spans with a prestressed concrete girder superstructure. The girders used on the project ranged from AASHTO Type II beams to modified Bulb Tee 74” beams. Responsibilities included lead bridge design, seismic analysis, and construction support.
  • Western Wake Freeway Design-Build, Wake County, NC: The Design-Build Western Wake Freeway project consisted of a new toll road that spans 12.6 miles located west of Raleigh, North Carolina. The project was part of the North Carolina Turnpike Authority’s Triangle Expressway, which is one of the first U.S. toll roads to use only electronic toll collection. The 12.6-mile toll road of full depth concrete pavement included 34 bridge structures with aesthetic treatments, 14 reinforced concrete box culverts, 6 new interchanges, noise walls, an extensive drainage network, and signage along the freeway. Responsibilities included lead roadway design, overall plan production management, final design and plans for 3 bridge structures, drainage design, erosion and sediment control, and MOT.
  • I-40 / I-440 Reconstruction Project (Fortify), Raleigh, NC: Provided lead design management for this design-build project that consists of rebuilding approximately 12 miles of interstate along the southern leg of the Raleigh inner loop. Pavement reconstruction, along with adding additional auxiliary lanes in select locations, will provide a safer riding surface and improve traffic operations along the corridor. The project involves reconstructing six interchanges, widening ten interstate bridges, and an extensive roadway drainage system upgrade.

  • I-385 Reconstruction, Laurens County, SC: This 15-mile project included the replacement of mainline interstate, raising 5 interchanges, and replacement of the I-385 NB overpass over I-26 E. To reduce construction time, the decision was made to detour all northbound traffic on I-385 for the duration of construction. This decision cut construction time in half and saved nearly $10 million on the overall project cost. As Engineer of Record, responsibilities included project management, QA/QC, utility coordination, and public involvement while with SCDOT.
  • Charleston County RoadWise Program, Charleston, SC: Program Management assignment for an $800 million road improvement program for Charleston County. Responsibilities included budget management, scheduling, and quality assurance, as well as coordinating all phases of the project with the County and SCDOT. This program was completed over a ten-year period.

S-128 N Pacolet 2

  • S-128 Bridge over North Pacolet River, Spartanburg County, SC: This project consisted of replacing the existing S-128 Bridge over North Pacolet River with a 3-span, 200-foot bridge. The existing structure experienced detrimental scour due to the migrating creek bank and its construction over a bend of the river. Much effort was taken to protect the outside river bank from erosion as well as the interior bent foundations from scour. As Engineer of Record, responsibilities included project management, multi-discipline design oversight, QA/QC, utility coordination, and public involvement while with SCDOT.
  • SC 183 Pete Hollis Boulevard (Western Corridor) Widening and New Location, Greenville, SC: This project consisted of the widening of an existing 5-lane roadway and construction on new location of a 7-lane facility through a densely populated area of downtown Greenville. This 4-mile project included two structures – one bridge over the Norfolk Southern RR and another bridge over Reedy River. While the railroad bridge would be built on new alignment and without the interference of traffic, the new 140-foot structure over Reedy River had to be built in stages and under traffic conditions. To complicate the Reedy River Bridge Replacement even further, the new structure was completed beneath a Duke Energy transmission line. Responsibilities included project management, QA/QC, multi-discipline design oversight, and public involvement while at SCDOT.
  • Construction and Resource Management (CRM) Program, Statewide, SC: Program Management assignment involved managing the development of 43 individual projects throughout South Carolina. CRM representatives were responsible for managing the projects, including schedule, budget, and quality, from the environmental phase to completion of construction.
  • Safe and Sound Bridge Improvement Project, Statewide, MO: This statewide accelerated bridge improvement program included the replacement of 554 structurally deficient bridges. In Missouri, 111 of the 114 counties had at least one bridge being replaced. The standardized precast superstructure and substructure components allowed the contractors to perform accelerated building techniques to speed up the construction time. The average construction duration of each bridge was only 45 days. Responsibilities included leading the design of 370 bridges.

  • Asbury Avenue Extension, Charlotte, NC: This project consisted of conceptual planning and design to determine the best alternate for extending this minor thoroughfare to Statesville Avenue. The road extension provided a vital connection between I-77 and North Graham Street in North Charlotte. Multiple alternates were studied with consideration for environmental factors, traffic flow, impacts to the Druid Hills Community, and stakeholder consensus. Responsibilities included an alternative analysis study, traffic analysis, public involvement, environmental permitting, final roadway design, and railroad/utility coordination.
