SUBJECT: Intersection of 83rd Ave. And 20th St.
Placement of Four-way Stop Signs
The Weld County Engineering Department has been asked to consider the placement of a four-way
stop at the intersection of 83rd Ave. and 20th St.
A recent traffic study revealed that there are sufficient warrants to change the signing from a two-
way stop to a four-way stop intersection.
The following is in reference to the Manual on Uniform Traffic Control Devices, Section 2B-6.
The manual states that multi-way stop signs should be placed only where the traffic on the
intersecting roads is approximately equal.
Any of the following conditions may warrant a multi-way STOP sign installation.
The warrants are:
1. Where traffic signals are warranted and urgently needed, the multi-way stop is an interim
measure that can be installed quickly to control traffic while arrangements are being made
for the signal installation.
2. An accident problem, as indicated by five or more reported accidents of a type susceptible
of correction by a multi-way stop installation in a twelve month period. Such accidents
include right and left turn collisions as well as right angle collisions.
3. Minimum traffic volumes:
A. The total vehicular volume entering the intersection from all approaches must
average at least 500 vehicle per hour for any 8 hours of an average day, and

B. The combined vehicular and pedestrian volume from the minor street or highway
must average at least 200 units per hour for the same 8 hours, with an average delay
to the minor street vehicular traffic of at least 30 seconds per vehicle during the
maximum hour, but
C. When the 85-percentile approach speed of the major street traffic exceeds 40 miles
per hour, the minimum vehicular volume warrant is 70 percent of the above
requirements.
The Colorado State patrol has reported that five accidents have occurred between February 6, 1997,
and November 3, 1997 at this intersection. Therefore,the warrant for the accident history has been
met.
It is my recommendation that a four-way stop be installed. Additionally, I recommend that
following traffic control devices be installed to match the existing installation at 20th Street and 71st
Avenue:
Rumble strips on 83rd Avenue
Painted stop bars
Painted stop ahead
36" stop sign
Temporarily flag new signs on 83rd Avenue.
