State Route 227 and Los Ranchos Road Intersection Operational Improvements Project
The County of San Luis Obispo is in the preliminary engineering phase of a project to improve operations at the State Route 227 and Los Ranchos Road intersections. In order to determine the best solution at this intersection, the County is working to perform a detailed traffic analysis of the State Route 227 corridor from Aero Drive to Price Canyon Road.
July 14, 2020 - The topographic survey, geotechnical explorations, and traffic forecasting is complete. Work continues to analyze each corridor alternatives under current and future traffic volumes. The County hope to present the findings of the traffic analysis to the community this fall/winter.
November 19, 2019 - The San Obispo County Board of Supervisors approved Phase 1 of a professional consultant services contract with Rick Engineering Company. The Board Agenda is available for review at: https://www.slocounty.ca.gov/Departments/Board-of-Supervisors/Board-Meetings,-Agendas-and-Minutes.aspx
March 20, 2019 - The first townhall meeting was held at Los Ranchos Elementary School. Representatives from the County, Caltrans, and SLOCOG were present to inform the public about the proposed project and hear their comments and concerns.
The Project is funded through federal Congestion Mitigation Air Quality (CMAQ) program funds and State Highway Account (SHA) funds programmed through the San Luis Obispo Counsel of Governments (SLOCOG).
In 2015, the San Luis Obispo Council of Governments (SLOCOG) initiated a corridor study to develop solutions to growing congestion on State Route 227 between Tank Farm Road and Price Canyon Road. The study included analysis of the following two possible solutions for the corridor:
1. Widening of State Route 227 to 2-lanes in each direction and upgrading the signals at various intersections
2. Constructing a series of roundabouts at key intersections
SLOCOG held three workshops during the development of the study to gain input from the public regarding the two alternatives. To improve operations by relieving existing and future congestion, the study recommended constructing a series of roundabouts, starting with Los Ranchos Road as a priority project, followed by Buckley Road. The SLOCOG Board approved the Study in December of 2016.
Additional information regarding the operations study can be found at SLOCOG's website.

Frequently Asked Questions
What are some common myths about roundabouts?
Are roundabouts safer than traffic signals?
Roundabouts are proven to reduce injury and fatal crashes compared to traditional intersections. Roundabouts are effective at slowing down traffic so that when crashes do occur, they usually occur at low speeds and are unlikely to cause injury or major damage. Roundabouts are also able to prevent head-on and T-bone types of crashes.
What should you do if an emergency vehicle is approaching?
- If you have not entered the roundabout, pull over and allow emergency vehicles to pass.
- If you have entered the roundabout, proceed to your desired exit, exit the roundabout, and the pull over to allow the emergency vehicle to pass.
- Avoid stopping in the roundabout since this could prevent the emergency vehicles from passing and prevent other vehicles from exiting the roundabout.
How do pedestrian cross at a roundabout?
Pedestrians should follow a few rules when crossing any roundabout:
- Cross the road to the median, using it as a refuge area to wait for a safe gap.
- Always look for vehicles and make sure that all motorists can see you. Never assume that a motorist can see you or intends to stop for you.
Stay on the sidewalk. Never walk in the roundabout or cross to the circular island.
How do bicycles navigate a roundabout?
There are no bicycle lanes within a roundabout. When the bike lane ends, bicycles have two options when approaching a roundabout depending on their comfort level:
- Bicyclists may merge with vehicular traffic and travel around the roundabout following all the same rules as a vehicle.
- Bicyclists may exit using the shared-use paths and crosswalks, following the same rules as pedestrians.
