Roadway Design    

Location: Home > Roadway Design

EST’s Roadway Division has four separate design teams. The design teams have performed work for a variety of clients including City, County and State Governments and Agencies. EST’s Roadway design portfolio includes complex multi-lane highways, interstate interchanges, city streets and intersections. EST has the ability to provide our clients with complete, comprehensive roadway design services beginning with the initial survey and concluding with construction management on the project. EST is thoroughly familiar with all Federal, State, City and local design standards and guidelines and will work closely with our clients to ensure a successful project completion.

The Design Team operates as the focal point for the development of roadway projects including the preparation of plans, the preparation of special provisions, the project schedule and coordination with other units and outside agencies. The team performs most of the analyses for road design, prepare reports, gain input from other divisions and perform the necessary drafting work for the preparation of in-house project plans. The design teams develop the project survey line and limits and are responsible for the design of all roadway drainage design, including cross drainage structures which are not classified as bridges. The design teams coordinate with utility and railroad companies through the appropriate Divisions for proper integration into road design plans.

FEATURED PROJECTS:

  • Highway 51 Intersection Reconstruction at Houston Street - Location: Broken Arrow (Tulsa County)

Customer/Client: City of Broken Arrow in collaboration with the Indian Nations Council of Governments (INCOG) and ODOT
Project Number: STP-173B(056)IG
J/P Number: 18434(04)
Contact: Joseph Watt, P.E., (918) 251-5311
Project Location: Broken Arrow (Tulsa County)
Estimated Cost: $2,588,500.00
Bid Price: Design Phase
This project is part of an effort between the City of Broken Arrow, INCOG, and ODOT to reconstruct intersection roadway structures to better handle the increase in traffic flow associated with local business growth. This intersection project will consist of new traffic signalization and roadway structures to handle a larger volume of traffic as well as improvements to drainage and grade. Existing roadway structures will be replaced with new surfacing and will be widened for new turn bays. Drainage improvements will consist of new curb and gutter flow structures to better handle storm water drain off and increase safety. In addition, a new detection system at the traffic signals will be installed to enable emergency vehicles to go through the intersection without stopping.

  • Highway 59 Improvement Project - Location: Town of Westville (Adair County)

Customer: ODOT
Contact: Darren Saliba, P.E., (918) 687-5407
Project Location: Town of Westville (Adair County)
Estimated Cost: $5,000,000

Approximately 2 miles of five lane widening and new alignment of US Highway 59 with an Intersection Improvement with US Highway 62 in Westville, Adair County. Project consisted of completing comprehensive roadway construction plans for the Oklahoma Department of Transportation. Half of the project was designed as an urban street with curb and gutter and the other half was designed as a five-lane rural highway with shoulders. The intersection with US 62 is included for modifications to include left turn lanes. Design included, but not limited to, survey, construction plans, right-of-way plans, utility relocation coordination, roadway alignment, drainage, traffic signals, signing, stripping, cross sections, and right-of-way plans. This project was located in an urban setting with multifaceted construction sequencing.

  • Highway 77 & Coltrane Road - Location: Edmond (Oklahoma County)

Customer/Client: City of Edmond in collaboration with ODOT
Project Number: STP-55A(938)AG
J/P Number: 15685(04)
Contact: Steve Lawrence, P.E., (405) 359-4798
Project Location: Edmond (Oklahoma County)
Estimated Cost: $2,078,995.85
Bid Price: $2,209,672.52
This project consisted of providing engineering services for the design of the US Highway 77 and Coltrane Intersection Improvements, which included two box bridges and traffic signals with water line and sewer line relocation in Edmond. Modifications to the intersection were needed to accommodate four-lanes, left turn lanes, and new traffic signals. The existing intersection was in the one-hundred (100) year flood plain and was raised out of the flood plain by designing reinforced concrete box structures to accommodate the water flows underneath the roadway. A flood plain study (FEMA LOMR) and FEMA Letter of Map Revision was done to accomplish this goal. Downstream channel improvements were necessary. The utility relocation plans were prepared for city owned water and sewer lines. Project also included sidewalks and cross walks.

  • U.S. 81 South Connection Bypass - Location: Near Duncan (Stephens County)

Customer: ODOT
Project Number: NHY-011N(057)
J/P Number: 20316(04)
Contact: Tracy Majors, (405) 522-7605
Project Location: Near Duncan (Stephens County)
Estimated Cost: $5,000,000
This project consists of the complete design of bridge and roadway structures associated with new construction along the U.S. 81 corridor. The new construction will include two miles of new roadway structures with two span bridges and four box structures. Also included are two curved ramps with steel plate girder substructure connected to a new half diamond interchange. The superstructure will be modeled three dimensionally in accordance with the AASHTO Guide Specifications for Horizontally Curved Highway Bridges.

  • U.S. Highway 75 - Location: Okmulgee (Okmulgee County)

Customer/Client: ODOT
Project Number: CIP-156H(013)HP
J/P Number: 14997(04)
Contact: Darren Saliba, P.E., (918) 687-5407
Project Location: Okmulgee (Okmulgee County)
Estimated Cost: $3,966,843.14
Bid Price: $4,395,339.94
This project consisted of 1.8 miles of five lane widening with two intersection improvements along US Highway 75 near Okmulgee. US 75 is a heavily traveled major highway connecting Tulsa to the Indian Nation Turnpike located within the city limits of the City of Okmulgee. In addition, the project was composed of new four-lane roadway with curb and gutter and a divided median with left turn bays at intersections. Drainage improvements beginning from 6th street to the North city limits were also designed along with traffic signals and school zone warnings. A new detection system at traffic signals was installed to enable emergency vehicles to go through the intersection without stopping. The existing highway was built without any super-elevation for the curves. The project’s terrain being flat with numerous flow line elevation restrictions on both sides of the highway posed a severe challenge to the designers in the handling of the drainage design.
