Holman Highway 68 Roundabout

Print

The Holman Highway 68 Roundabout will relieve congestion at the busy intersection of Holman Highway 68, Highway 1 ramps and 17 Mile Drive near the entrance to Pebble Beach and the Community Hospital. This project is the result of a collaborative effort and a public-private partnership between the City of Monterey, Pebble Beach Company, Monterey Bay Unified Air Pollution Control District, County of Monterey, City of Pacific Grove, Caltrans and the Transportation Agency for Monterey County.

Construction Updates

This Week (April 23-28) 

This week, crews worked around the rain early in the week, and were able to finish the required paving work in order to move into the next stage of construction.

There will be one an additional night of work with traffic detours on Sunday April 23 in order to switch to the next stage of construction (depending on the weather). Following this work, the construction will enter the next stage of construction starting at 6 a.m. on Monday morning.

During the next stage of construction, additional congestion is expected in the eastbound direction along Holman Highway 68 because there will not be a dedicated right turn lane towards the southbound Highway 1 on-ramp.

Also starting on Monday at 6 a.m., there will be no left turn out of the Pebble Beach Highway 1 Gate for approximately 5 weeks. This no left turn restriction will be in place 24 hours a day for the 5 week period.

Here’s what you need to know for entering and leaving Pebble Beach during the 5 week left turn restriction:

  • Highway 1 gate exit will be right turn only
  • Highway 1 gate entrance will remain fully open
  • To get to northbound Hwy 1 or westbound Holman Hwy 68, all drivers will need to use another gate, or the detour route.

Leaving the Forest to go north on Highway 1?

  • Remember, the Morse Gate is always a
    right-turn-only exit and an easy route.
  • Alternatively, use the Carmel Gate

Leaving the Forest going to Pacific Grove or CHOMP?

  • Use the Carmel gate or one of the Pacific
    Grove gates.

Do’s & Don’ts

  • Don’t try to get to Pacific Grove or CHOMP from the Highway 1 Gate.
  • Do use the Carmel Gate or one of the Pacific Grove Gates.
  • Don’t end up in the congested detour route.
  • Do plan ahead and avoid the intersection!

EXPECTED CLOSURES & DETOURS:

Below is the projected schedule; however, this schedule is dependent on the weather, and rain may delay the closures.  To receive the most recent information on closures and detours please sign up for text alerts and email blasts (more information below).  Detour signage will be in place including signage to the hospital. Plan to use alternate routes and avoid the intersection whenever possible. 

  • Day Work:
    Next week daytime work will continue behind the barriers and is not expected to directly impact the traveling public. Additional congestion is expected in the eastbound direction along Holman Highway 68 because there will not be a dedicated right turn lane towards the southbound Highway 1 on-ramp.
    Sunday April 23 (8 p.m. – 6 a.m.)
    The southbound Highway 1 on-ramp will be closed between Highway 68 and the Pebble Beach Gate. The Highway 1 Gate entrance to Pebble Beach will be CLOSED; all other gates will be open. The Highway 1 Gate exit from Pebble Beach will be a right turn only.Southbound Highway off-ramp to Holman Highway 68 will be closed.

    For those leaving Pebble Beach wanting to access Highway 68 or northbound Highway 1:  Use an alternate gate (recommended); Or – turn right out of the Highway 1 Gate to access southbound Highway 1 and turn around at Carpenter Street or Ocean Avenue.

    Detour signage to use Morse gate for Pebble Beach access will be posted.

    Those exiting southbound Highway 1 to Holman Highway 68: Continue south on Highway 1 and make a U-turn at either Carpenter Road or Ocean Ave. and return to Holman Highway 68 via the northbound Highway 1 off-ramp. Map: Highway 68 / Southbound Highway 1 Off Ramp Detour map

    Those trying to get to Highway 1 south from Holman Highway 68: Take the northbound Highway 1 exit and turn around at Munras Avenue.  Large vehicles and trucks will need to turn around at Aguajito Road. Map: Highway 68 / Southbound Highway 1 On Ramp Detour Map

Goals

  • Relieve existing and future traffic congestion
  • Improve traffic safety
  • Improve traffic operations
  • Minimize delay of emergency vehicle access to the Community Hospital
  • Reduce bypass traffic through the Skyline Forest Neighborhood
  • Improve access to Pebble Beach, Community Hospital and Beverly Manor Development

Project History & Background Resources

Project History

The existing signalized intersection at Holman Highway 68 and Highway 1 ramps experiences unacceptable peak hour congestion.  Congestion at this location is costly to residents, visitors and businesses and delays emergency vehicles going to and from the Community Hospital. Surrounding neighborhoods have also suffered from cut-through traffic, a byproduct of congestion on Holman Highway 68. In 2009 Caltrans adopted a project report that included upgrading the signalized intersection and widening of Holman Highway 68.

The City began to seek out alternatives to the signalized intersection and conducted a roundabout feasibility study in 2011-2012 using an Air District Grant (AB 2766 grant).  The study showed that compared with the signalized intersection option, a roundabout option is:

  • Safer
  • Less Expensive
  • More Efficient
  • Cleaner (less air pollution)
  • More environmentally friendly (will save hundreds of Monterey Pine trees)

In 2013, the City conducted an intersection control evaluation (ICE) to confirm that a roundabout would work at the intersection of Holman Highway and 17 Mile Drive.  The evaluation revealed that the roundabout design can accommodate existing and future demand.

The project is now fully funded using a combination of state, regional and local sources.  The project has received funding from the Monterey Bay Unified Air Pollution Control District, Transportation Agency for Monterey County and Pebble Beach Company.

Public Outreach

The goals of the public outreach and education campaign are to:

  • Spark internal and external stakeholders’ interest
  • Increase understanding of the benefits of a roundabout
  • Provide basic “how-to” instructions so that travelers will be confident when navigating the roundabout for the first time
  • Provide an environment that is comfortable and secure for asking questions
  • Tailor outreach strategies to address local concerns

The campaign will occur in two phases. The first phase will provide basic information about the project background, purpose and schedule , and general education about roundabouts. The second phase will provide information on staging and construction.

Roundabout Signs and Navigation

Wayfinding signage is an important component of the Holman Highway 68 Roundabout and will help travelers navigate through the intersection to their desired destination. Below are examples of two types of signs that will be visible at the approach to the roundabout and at exits.
