Carpenter Marty Transportation

At Carpenter Marty Transportation (CM), our success is driven by employees that strive for excellence. Our company was founded to raise the standards in transportation engineering. We focus on exceeding expectations, not making a profit. By keeping this our core value, we have established and maintained strong working relationships with local municipalities, counties, and Ohio Department of Transportation (ODOT) district offices for more than 24 years.

Our Ohio-headquartered team has extensive experience with local and state standards and are available to promptly respond to your needs. We are experts in bridge, roadway, traffic, survey, and right-of-way design services.
