Engineering Vibrant and Connected Communities
TWM is considered one of the top pedestrian and bikeway trail planning and design firms serving southern Illinois and Missouri. We have partnered with public agencies and private developers to create more than 35 miles of multi-use trails over the last 10 years. Whether it’s for work or play, our trails are designed with aesthetics, functionality, and cost-effectiveness in mind.
When designing trails, we take a collaborative approach to ensure we clearly understand your short- and long-term goals for the community, your vision for the current project, as well as your plans for future growth. Applying this method has enabled us to consistently achieve our clients’ benchmarks for success during each phase of their projects.
