New Roundabouts Opened This Fall
It is always exciting when a roundabout finally opens to the public after the dedicated effort of so many involved to bring these challenging projects to fruition. MTJ's extensive traffic planning and roundabout experience ensures successful, well-received projects, including these:
Main St. and Century Ave. (STH 119/113) Roundabout â€“ Waunakee, WI â€“ see video
MTJ provided to WisDOT the roundabout capacity analysis, traffic planning, final horizontal design, feasibility, and public outreach support for this signal-to-roundabout conversion project located in an urban constrained intersection. The final urban, pedestrian-friendly roundabout design anchors a downtown Complete Street revitalization project that incorporates a three-lane section with flared entries on all legs, accommodating ~ 27,000 ADT. The roundabout allowed for maintaining existing business access and circulation, improved traffic flow, as well as large truck and oversize/overweight specialty freight carriers.
Cty M and Brookfield Rd. Roundabout â€“ Brookfield, WI
MTJ provided to Waukesha County Highway Engineering Dept. the roundabout traffic analysis, horizontal design, and design review for this very congested all-way-stop conversion to roundabout project. The highly constrained roundabout accommodates large truck movements and provides a safe roundabout for non-motorized users. Key to this effort was minimizing impacts to historical and other adjacent residential land uses, and balancing significant vertical roadway constraints.
Johnsburg and N. Chapel Hill Roads Roundabout â€“ Johnsburg, IL
The Johnsburg roundabout was the first in McHenry County, IL. MTJ Roundabout Engineering provided to the County a unique non-circular roundabout design for this highly constrained urban intersection and roadway reconstruction project. This project was part of a multi-million dollar reconstruct, and included geometric design optimizations as well as pavement marking and signing reviews.
Main (STH 62) and Market Streets Roundabout â€“ New Albany, OH
MTJ provided Peer Review and design optimization services to the City of New Albany to achieve a pedestrian optimized design that meets operational objectives, accommodates large truck movements, maximizes on-street parking, and meets Complete Street objectives. The MTJ-recommended design provided a more compact, slower/safer, pedestrian-friendly urban roundabout, with landscaping features to assist way-finding by guiding pedestrians to the correct crossing locations, precluding unsafe crossings.
Rocklin Road Corridor â€“ Rocklin, CA
MTJ, with partner firm Omni-Means of California, transformed the Rocklin Road five-lane, heavily congested, commercial arterial into a series of seven roundabouts, with the first two now open. Utilizing the unique operational characteristics of roundabouts allowed for an impressive transformation of this corridor into a Complete Street. The roundabout design provided improvements to business access and circulation, minimal impacts, and significant improvements to the pedestrian environment and overall aesthetics of this main entrance to the City.
