MTJ (as part of the Lee Engineering team) evaluated the feasibility of two roundabout applications at these highly constrained sites. MTJ Roundabout Engineering developed multiple geometric designs for the evaluation of feasibility.

This TAMC/Caltrans-led project provided roundabout solutions for the interchange at Fremont Blvd., SR 1, California Ave. and Monterey Rd. that serves Monterey County, CA.

MTJ Roundabout Engineering’s Mark Johnson was the designer/reviewer responsible for operational analysis and final horizontal geometrics for this roundabout serving a major interstate. This challenging roundabout project includes two 6-leg interchange ramp terminal roundabouts.

MTJ Roundabout Engineering, working as part of a team with Omni-Means, designed these interchanges in the City of Farmersville, CA. The city had a specific plan area encompassing the SR 198/Farmersville Boulevard interchange. The cost to update this interchange with conventional signalized and associated roadway widening was a detriment to the advancement of this plan.

MTJ Engineering’s Mark T. Johnson, P.E., as a sub-consultant to Hurley and Stewart, Inc., provided the Roundabout Analysis, Pedestrian Facilities Design and Final Horizontal Design for this intersection alternatives analysis project located adjacent to Western Michigan University.

In 2005 MTJ began working with the developer’s traffic consultant to find an acceptable access solution for the proposed commercial development at USH 18 and STH 83, which was a signalized intersection at the time.

MTJ Roundabout Engineering’s Mark Johnson, serving as a sub-consultant to R.A. Smith National, provided the capacity analysis, final horizontal designs, and peer review for this complex system of four roundabouts that feature single-lane to three-lane entries.
