ROADWAY & HIGHWAY
CFS Engineers provides premium planning, design, and inspection for all aspects of highway projects. To achieve the best quality for a design project, our team plans and designs for horizontal and vertical alignments, topography constraints, clear zone grading and guardrail protection, traffic signals and roundabouts, signage, pavement markings, and access management. We expertly cover the variety of roadside details for highway projects including landscaping, stormwater flow, erosion control, lighting and fiber, and Intelligent Transportation Systems (ITS).
PROJECTS
91st Street
De Soto, Kansas
The 91st Street Extension project extended from existing 91st Street west to Sunflower Road, constructing approximately 2,500 feet of new roadway. This project was a cost share between the City of De Soto and the Johnson County CARS program. The 32-foot wide street consisted of two 11 ft travel lanes and two 5 ft bike lanes with concrete curbs and gutters, with an 8 ft wide multi-use path and a 5 ft sidewalk. This project provided vehicular and pedestrian access to the recently opened Lexington Lake Park at Sunflower Road and serves as an alternative route to the Unified School District No. 232 campus, located in the northwest quadrant of 91st Street and Lexington Avenue. Work included clearing and grubbing, grading, storm sewer, paving, erosion control, utility conduit, fencing, permanent seeding, pavement marking, permanent signing, and traffic control. The project was bid on time and under budget.
CFS provided project management, topographical and boundary surveys, right-of-way and easement legal descriptions and exhibits, civil engineering design, stormwater design, and construction engineering services. All analysis and design activities were performed and construction plans prepared in accordance with KCAPWA and KDOT technical specifications and requirements. CFS provided sealed construction plans and specifications enabling the City to obtain a competitive bid for this project.
155th Street Improvements
Kansas City, Missouri
The CFS Team was selected by the City of Kansas City to design major improvements for the 155th Street corridor. These improvements were necessary due to the tremendous redevelopment taking place in this area. The design included the reconstruction of 3,500 feet of roadway along 155th Street from Kensington Avenue to the Kansas City Southern Railroad Crossing. Along with the roadway improvements the project includes the construction of a 10’ Trail with accessible ramps, and a 5' sidewalk with accessible ramps. Other features within the project are: 2-28’ wide divided median roadway sections, 127’ long 6’x6’ box culvert, 26 storm inlets, 3,200 linear feet of storm pipe utility relocations, and 60,000 cubic yards of earthwork.
For this project CFS was contracted to complete surveying, roadway design, street Lighting Design, Storm Sewer Design, Erosion Control Design/NPDES and MDNR Permitting, Storm Water Detention, BMP Analysis and Design in Accordance with the MARC BMP Manual, Right of Way Acquisition and Easement Preparation, Bid Document/Project Specification Preparation, Cost Estimating, and Construction Administration/Bid Services.
For this project CFS incorporated the latest 3D modeling techniques within Microstation to create a complete 3 dimensional representation of the proposed project. The 3D models included roadway, trail, sidewalks, tie slopes, driveways, ADA ramps and sidewalk ADA crossings, retaining walls and storm sewer.
Route 1 and Parvin Road Roundabout
Kansas City, Missouri / MoDOT
The project was focused around the intersection of Missouri Route 1 (Prather Road) and Parvin Road in Clay County, Missouri. The 4-way stop condition intersection was reconfigured to a single lane roundabout with a 130’ inscribed circle and truck aprons inside and outside of the circle to accommodate the WB-67 design vehicle. The City of Kansas City, Missouri was a partner in the project providing a local match to the transportation funding. Both the KCMO Parks Department and the Public Works Department each have property adjacent to the project and were active in the planning and development of the project.
Construction includes clearing, removal of improvements, grading, enclosed storm sewer system, paving, retaining walls, erosion control, street lighting, permanent signing, and pavement markings. The project includes approximately 1,400 linear feet of roadway reconstruction, including a 5’ cut in one leg of the intersection which has required significant utility coordination and relocation.
MoDOT selected CFS to provide construction documents for improvements to the intersection. CFS provided topographic and boundary survey for the project. CFS has provided roadway final design and final PS&E package for construction letting. These services included geotechnical services, survey, and utility coordination. CFS was also responsible for providing displays / layouts and information for Right-of-Way acquisition, environmental studies & permits, and a public meeting.

Kentucky Road Extension
Raymore, Missouri
This project was a roadway extension/realignment design with the goals of minimizing impacts to adjacent properties and the nearby wetland areas, providing legal descriptions and exhibits for required easements and right-of-way, and maintaining a consistent speed of 35 mph to better serve traffic conditions. The new roadway connection reduced congestion and safety risks with traffic directed away from an offset stop-controlled intersection to a nearby existing signalized intersection.
The proposed alignment developed by CFS Engineers included many complete street enhancements such as right-turn lanes, a 10 foot shared-use path, street lighting, replacing faded pavement markings, and Best Management Practices (BMPs) for controlling stormwater. To visually de-emphasize the connection of the new alignment to the old north-south alignment, the new alignment was curved at a 4 percent superelevation tilted away from the connection and the connection included a separation island to limit a continuous wide opening.
CFS tasks included survey, preliminary design plans, identifying utility conflicts, subsurface investigation, cost estimation, meetings with property owners and City staff, detailed storm drainage analysis and BMP analysis, preparation of legal descriptions and exhibits for required easements and right-of-way, and preparation of final plans, specifications, and the SWPPP.
