Holman Highway Project Named “Best Use of Government Funds”

Editors at the Monterey County Weekly have named the Holman Highway 68 roundabout as their county’s “Best Use of Government Funds” in 2017.

The locally owned Seaside, California-based newspaper featured the project in its “Best of Monterey County” annual issue, which was published on March 22, 2018.

The roundabout, which replaced a congested intersection and serves as primary access to Pebble Beach and Community Hospital, has “radically improved the quality of the commute life for thousands of travelers,” the paper said.

Congratulations to all our partners who worked on this exciting, challenging project.

Mark Johnson Presenting at OTEC

OTEC logoMark Johnson, PE will be presenting at the Ohio Transportation Engineering Conference in Columbus, OH. His presentation “Too Many Crashes at Your Multi-Lane Roundabouts? Learn How to Optimize Safety for Multi-Lane Roundabouts” will be on Oct. 11 at 8am.

Session 49 – More About Roundabouts
Room: A110-112

Multi-lane roundabouts are having excessive PDO or minor crashes, which is creating many challenges for implementation. This presentation details the essential components for designing optimal roundabout safety and operations, and highlights how these elements blend together that affects how drivers process that information and then react to it.

See you there at this topical presentation!


Mark Johnson Presenting at TRB Webinar

Mark Johnson will be presenting at the TRB webinar “Modern Roundabouts: Downtown and Suburban Revitalization.

The webinar will be on Monday, September 18, 2017, from 2:00 PM to 4:00 PM ET and will provide examples of ways the modern roundabout may be able to revitalize a downtown area, enhance a community’s sense of place, and provide a safer and more efficient traffic flow in urban and suburban areas. Presenters will describe how roundabouts have jumpstarted downtown revitalization, illustrate how roundabouts have enhanced communities, and demonstrate how roundabouts have improved traffic flow.

Two PDH credits are available. For more information or to register see TRB’s webinar page.

Breckenridge, CO Roundabout Now Open

The first roundabout on the Park Ave. Corridor in the Town of Breckenridge, CO is now open! The roundabout at 4 O’Clock Road and Park Avenue held its opening ceremony on June 30, 2017. 

This is the first roundabout planned along a corridor of nine roundabouts on Park Avenue (SH 9). MTJ Roundabout Engineering worked with the Town of Breckenridge, CO and McDowell Engineering on the peer review for this project.

Roundabouts and Access Management Webinar


Mark Johnson, P.E., will be presenting in the TRB Webinar: “The Marriage of Roundabouts and Access Management” on Sept. 26, 2016, 2:00-3:30 PM ET.

Case Studies: Roundabouts and Business Access
MTJ will present case studies of high flow multi-lane roundabouts that illustrate how the application of traffic engineering and roundabout design principles can harness the unique operational characteristics of roundabouts to facilitate improved traffic flow, safety, and excellent business access.

Webinar Outline

  • Overview of access management techniques and roundabout characteristics
  • Discussion of case studies
  • Installation of raised medians and roundabouts through densely developed corridor
  • How roundabouts can eliminate access management problems
  • Achievement of access management goals with roundabouts
  • Question and answer session
