ODOT STW Safety Studies
"Lanham Engineering has served as a prime consultant on ODOT’s Statewide Safety Studies contract for the past eight years, recently winning our fifth consecutive contract. We have been assigned over three dozen studies during that time that included a mix of abbreviated and formal studies. Although the process is similar for each study, the Lanham team prides ourselves on treating each study as a unique entity requiring unique solutions."
City of Columbus – Downtown Signals Part 2
"In our first City of Columbus prime contract, we are currently designing the replacement of existing traffic signals at the intersections of Rich Street at 3rd Street, 4th Street, 5th Street, and Grant Avenue with new decorative mast arm traffic signals, brick intersection corners, decorative street lighting, and interconnect. Traffic will be maintained during construction through temporary signals and closing curb lanes. The project includes public involvement and environmental efforts, roadway design of new brick sidewalk and curb ramps at each intersection, and storm sewer replacements at various locations."
COTA West Broad Street BRT Corridor
"The Central Ohio Transit Authority plans to implement a Bus-Rapid-Transit system along West Broad Street as part of the LinkUS Mobility Initiative, a transformational vision for growth and mobility in Columbus. The design phase of the project is ongoing, with 90% plans currently being under design. Our design work consists of signing and marking design to current OMUTCD standards, and replacement or modification of 22 traffic signals. Portions of the corridor will be widened and warrant a complete reconstruction of the signals, while others will undergo modifications to implement lane usage changes and apply bus rapid transit priority treatments."
LOR-CR1-12.28
"This LPA project in Lorain County at the N. Ridge Road and Elyria Avenue intersection replaced an existing traffic signal with a new mast-arm design, LED signal heads, radar detection, a new controller cabinet with UPS, and updated signing/markings to current OMUTCD standards. Additionally, there was some minor roadway work including replacing curb lines, new asphalt for the conduit crossings, and resurfacing the intersection."
HAM-75-1.95
"I-75 is being reconstructed on the south side of Cincinnati, with this project spanning from Findlay Street to Marshall Avenue and including connection to the new Western Hills Viaduct project. Lanham’s work includes 1.5 miles of signing and pavement marking plans. It contains over 20 overhead sign supports and traffic control design of five interchange ramp intersections."
East Broad Street Widening Phase 2
"The project is the second phase of a major widening project that will construct new through and turn lanes along the Broad Street corridor from the east side of the I-270 interchange to the intersection with Reynoldsburg-New Albany Road. The Broad Street improvements will consists of widening for turn lanes, additional through lanes in each direction with new curb, sidewalk, and a shared use path, including raised medians to create a safer corridor. Our design work consists of the signing and marking design, temporary and permanent traffic signal/interconnect design, and lighting for the corridor."
CUY-480–06.12
"This project consists of replacing the existing bridge deck and raising the clearance above I-480 in Cuyahoga County near Fairview Park. The improvements to the bridge will also include minor roadway work to upgrade lighting, signing and pavement markings and signals along the West 220th Street bridge span. Our design work includes the design of pilaster mounted light poles connected to a conduit system within the bridge structure that ties into existing overhead lighting."

ODOT STW Design Traffic
"The purpose of this contract is to develop certified traffic on a task order basis for various projects throughout the state. Lanham Engineering is currently holding this statewide design traffic contract for the third straight time. This ongoing contract has been largely managed by Kristi Norfolk, serving as lead engineer with junior engineers working alongside her on most tasks. The most challenging recent task was FRA-161-15.80, which involved developing forecasts along I-270 and SR-161 for improvements needed for the new Intel development. The forecasts were on an aggressive schedule considering there were six different model scenarios used, which was completed one week early."
STW Safety Studies – Subconsultant Contracts
"Through ODOT’s Statewide Safety program, we have served as a subconsultant under 13 different contracts with primes where we provided services ranging from traffic analysis support to full traffic studies. Throughout these contracts, we have worked on dozens of studies in all 12 Districts in Ohio, and plan to stay committed to serving the safety program."
City of Columbus – Safety Studies Contract
"As a subconsultant on three different task orders, Lanham Engineering provided traffic engineering services under the City of Columbus Safety Studies contracts. While many of the tasks are either safety studies or cursory reviews, we have been assigned to more broad safety-related tasks over the past six years. Other tasks included speed studies, sight distance triangle exhibits, preliminary design for marking improvements for bicycle and pedestrian facilities, and capacity analysis for a road diet."
North Knot Feasibility Study
"Lanham Engineering is currently collaborating to prepare a feasibility study for the North Knot (the area surrounding SR-315 between Goodale Avenue and North Broadway). The first task involved determining potential future pinch points in the network that was used during the charrette process to pinpoint areas that need to be included in future improvements. Our current tasks includes forecasting 2050 traffic volumes for the network including six interchanges and 34 intersections and submitting them for certified traffic approval. These volumes will be used in capacity analysis to narrow down alternatives to a preferred option to move forward into preliminary design."
MED-162–20.06
"This project involved the transformation of the all-way stop-controlled intersection into a single-lane roundabout. Our responsibilities encompassed the development of the Maintenance of Traffic plans and the lighting analysis and design. Utility coordination played a critical role in the design process, particularly with the relocation of a major overhead electric line that crossed both the west and south legs of the intersection near the roundabout's center island."
ODOT SR-161 Improvements for the Silicon Heartland - Interchange Operations Study
"ODOT plans to improve the SR-161 corridor leading to the Silicon Heartland to prepare for the incoming Intel microchip facility. Lanham Engineering has contributed to this effort by developing opening and design year traffic volumes. We also prepared an interchange study to analyze the capacity throughout the corridor to confirm that the proposed lane addition to SR-161 will improve traffic flow. We are currently forecasting additional traffic to the east of the Intel site for further development."
ODOT District 6 - FRA-33-6.15
"A 2019 safety study of the intersection of US-33 (Riverside Drive) at Hayden Run Road determined a need for an additional northbound left turn lane in order to reduce crashes, after the intersection was designated a high crash location on the Highway Safety Improvement Program (HSIP) in 2017. This project includes widening and radius work at the intersection to accommodate the dual left turn lanes. Our portion of the work included the signing and pavement marking design to current OMUTCD standards, maintenance of traffic plans for both vehicular and pedestrian traffic, and the replacement of the traffic signal."
Fishinger Road Phases 1 & 2 – Signal and Traffic Control Design
"Lanham Engineering is working as a subconsultant to provide construction plans for the reconstruction of Fishinger Road and addition of sidewalks and a shared use path between Tremont Road and Riverside Drive in Upper Arlington, Ohio. Our portion of work includes signing/pavement marking design to current OMUTCD standards for the entire corridor and signal design/modification upgrades at the Kioka Avenue, Mountview Road, and Reed Road intersections. We are also developing and designing Upper Arlington’s first fiber optic cable interconnect installation along the corridor, connecting the traffic signals for coordination and providing communication options for other City entities."
