Holman Highway RoundaboutMTJ Roundabout Engineering provided the roundabout traffic analysis, horizontal design optimization, and design oversight of pavement markings and signage for this project as a member of the consulting team led by Omni-Means.

The City of Monterey received a grant to prepare a concept design for a roundabout at this location. Several alternative designs were studied, including an underpass, and a final concept was included in the alternatives analysis of the Environmental Impact Report (EIR) for the Pebble Beach Company Plan as an alternative to the signalized intersection.

The alternatives analysis concluded that the roundabout alleviates the identified traffic impacts and is environmentally superior to the signalized intersection due to its smaller footprint in terms of tree loss and other biological impacts, ground disturbance, archaeological impacts, and visual impacts. Construction is due to begin after June 2015.

When compared with the option to upgrade the existing traffic signal, the City of Monterey concluded that the roundabout will be safer, less expensive, will reduce pollution, and save hundreds of Monterey pine trees.

The roundabout will provide access to Carmel, Pebble Beach, Pacific Grove, Monterey, and the Community Hospital (CHOMP).
