Stop Sign Modification Projects

There are several criteria to consider when evaluating whether an all-way stop is warranted. If a location meets the criteria, it will have higher compliance rates, thus reducing the crash potential. If the intersection does not meet all-way stop criteria, drivers tend to ignore unwarranted stop signs over time. When stop signs are ignored, they are no longer serving their purpose, which is to inform roadway users who has the right of way at an intersection, and crash potential increases. Additionally, unwarranted stop signs may provide a false sense of security for pedestrians expecting drivers to comply.

Project Number: CG4446

Intersection: W. Glasgow Avenue and S. Nelson Street 

Analysis: In 2019, Jefferson County installed a marked crosswalk leading to Eagle Meadows Park and a path to Ute Meadows Elementary School from the south. This crosswalk was at an all‐way stop. 

The county observed that drivers were not complying with the stop sign, endangering students walking to school and other pedestrians. The county’s analysis indicated that this was likely due to the stop signs not meeting the Manual of Uniform Traffic Control Devices (MUTCD) warrant threshold for an all‐way stop. 

Action: Jefferson County replaced the stop signs on the W. Glasgow Avenue approaches with School Crosswalk signs. School Crosswalk signs will inform drivers what type of traffic to expect, and of pedestrian right-of-way, without unwarranted stop signs which may be ignored if there isn't other vehicular traffic present. It is expected that the School Crosswalk signs will have better compliance than the existing stop signs, thereby improving the safety of the students / pedestrians. 

Status: Completed

Project Number: CG4876

Intersection: W. 54th Avenue and Pike Street

Analysis: A temporary all-way stop was put in place during a detour in conjunction with the McIntyre construction project. After this temporary measure was removed, staff analyzed whether a permanent all-way stop condition would be warranted. Jefferson County staff found that an all-way stop condition is not warranted at this location.

Action: No changes to current configuration. Pike Street will remain stop-controlled and W. 54th Avenue will remain free-flowing.  

Status: Not Applicable

Project Number: CG4997

Intersection: W. 10th Avenue and Zang Street

Analysis: Concern about confusion over stop sign placement 

Action: A stop bar will be added on the eastbound sign to make it more clear where motorists are required to stop.  

Status: Planned

Project Number: CG5188

Intersection: W. Berry Drive and S. Zinnia Street

Analysis: There is no traffic control at this intersection establishing which direction has the right-of-way. Upon further analysis, Jefferson County staff found this situation at several intersections in the neighborhood. 

Action: A complete review of intersections in the neighborhood was completed. 24 new stop signs will be installed.

Status: In Progress

Project Number: CG5201

Intersection: W. Stanford Avenue and S. Alkire Street

Analysis: Current configuration: two-way stop control with Stanford stopped and Alkire free-flowing. County staff observed low compliance at the stop signs on Stanford, causing a potential conflict situation. Jefferson County staff analyzed the intersection and found that it does not warrant an all-way stop. Analysis also found that the east-west direction (W. Stanford Avenue) had higher approach volumes than the north-south direction (S. Alkire Street).

Action: Due to higher approach volumes on Stanford, and low compliance which may be due to an unexpected stop condition, change intersection configuration to: S. Alkire Street two-way stop controlled, W. Stanford Avenue free-flowing.  

Status: Planned

Project Number: CG5405

Intersection: W. 60th Avenue and Blanca Court 

Analysis: County staff observed low compliance at this all-way stop location. Analysis showed low volumes and it does not warrant an all-way stop. 

Action: Remove stop signs on the W. 60th Avenue approaches. 

Status: Planned

Project Number: CG5774

Intersection: W. Belmont Drive and S. Taft Street

Analysis: A neighborhood review of the Trapper’s Pond / Simms Pointe area resulted in all stop signs in compliance with MUTCD standards except for the sign at the S. Taft Street approach to W. Belmont Drive.

Action: Adjust the Stop Sign at the S. Taft Street approach to W. Belmont Drive to a compliant height and make other adjustments to street name signs in the area.

Status: Planned

Project Number: CG5922

Intersection: W. 50th Avenue and Quaker Street / Quaker Lane

Analysis: County staff observed low compliance at this all-way stop location. Visibility measures, such as “Stop Ahead” warning signs are in place for the W. 50th Avenue direction. Analysis shows low volumes in the north-south (Quaker) directions. This intersection does not warrant an all-way stop condition.  

Action: Working in collaboration with the City of Golden, remove the stop condition for the east-west direction, allowing W. 50th Avenue to be free-flowing.  

Status: Planned 

Back to top


Project Number: CG6010

Intersection: W. 30th Avenue and Crabapple Road 

Analysis: Based on volumes, this intersection does not warrant an All-Way Stop. There is an issue with compliance on the left-turn yield from Crabapple Road onto W. 30th Avenue.  

Action: Add warning signs showing the configuration of the intersection, clarifying the left turn, and establishing an advisory speed of 15 miles per hour (MPH).

Status: Planned

Project Number: CG6377

Intersection: S. Field Street and W. Prentice Avenue

Analysis: Concerns regarding motorists running the stop signs on S. Field Street resulted in conducting traffic counts. After collecting traffic data, it was determined that the four-way stop is not warranted.

Action: Jefferson County will replace the stop signs on the S. Field Street approaches with Crosswalk signs. Crosswalk signs will inform drivers what type of traffic to expect, and of pedestrian right-of-way, without unwarranted stop signs which may be ignored if there isn't other vehicular traffic present. It is expected that the Crosswalk signs will have better compliance than the existing stop signs, thereby improving the safety of pedestrians.

Status: Postponed due to greater concerns with traffic calming in the area.

Project Number: CG6410

Intersection: Stanley Park Road and High Drive / Stanley Park Road

Analysis: The Stanley Park Road cul-de-sac approaching High Drive as it turns into Stanley Park Road does not have any traffic control and it is not assigned who has the right-of-way to proceed through this intersection.

Action: Add a stop sign to the Stanley Park Road cul-de-sac approach to High Drive / Stanley Park Road 

Status: Planned

Back to top


Project Number: CG6574

Intersection: Sunset Trail and S. Noka Trail

Analysis: There is no traffic control or assigned right-of-way at this location (no stop or yield signage). Further analysis is underway. 

Action: S. Noka Trail is the lesser approach. Since there is no traffic control currently, add a Yield sign to the S. Noka Trail approach.  

Status: Planned
