TRANSPORTATION & TRAFFIC
When it comes to designing a transportation system involving traffic, streets, and highways, safety and efficiency are undeniably among the top priorities. But in today’s economy, the solutions to transportation challenges also need to be affordable. TWM focuses on helping our clients find the best alignment between effectiveness, efficiency, and economy. We strive for solutions that not only work, but also work “smart” and are within budget.
WHAT WE DO
TWM has a well-rounded team providing a full range of design and construction observation services, bringing our clients established relationships with reviewing agencies such as the DOT, DNR / NRC, and USACE. We have designed dozens of miles of state highways and local roadways in the past five years. We have completed traffic studies, held public meetings, negotiated purchase of land, and acquired necessary permits. TWM has designed several roundabouts, thousands of curb ramps, and the first diverging diamond interchange in IL.
Our expertise ranges from designing new alignments, reconstruction, and widening projects on interstates, rural and urban highways, local streets and bridges, bike trails and sidewalks, multi-modal enhancements, to simply assisting municipalities in planning their annual street maintenance programs. Cognizant that our clients always have budgets to meet, we strive for solutions that not only work, but also work smart.
