Existing delays at the location including various intersections
operating at Level of Service (LOS) “D” and “F” during certain peak
hours were becoming unsustainable and all intersections except SR
68/CHOMP were predicted to reach a LOS "F" by the year 2035. This
meant that the EB approach on SR 68 during morning peak will have
queues of 42 vehicles with similar queuing for the EB and WB
approach during PM peak after 2025. In order to mitigate this, we
prepared a transportation operations study to support the ICE
process and presented the results of conceptual alternatives.
Along the coast in the Monterey Peninsula, we prepared plans for
a roundabout solution for the SR 68 and SR 1 intersection. The
location serves as a gateway for the communities of Pacific Grove
and Pebble Beach, as well as the famous 17 Mile Drive. Our team
worked with a community partnership including the City of Monterey,
Caltrans, the Pebble Beach Company, and Monterey County, to improve
the intersection at SR 68 and SR 1 including the access to 17 Mile
The end result is a solution that addresses all of the unique
characteristics of the area. Reduced idling times for travelers due
to eliminating traffic signals and stop signs will improve traffic
flow and reduce GHG Emissions, providing an environmentally
friendly improvement in an area prized for its natural environment.
The clearly marked approaches into and out of the roundabout will
allow the many visitors to the area to easily navigate to any of
the several tourist destinations served by this access point.
