Quick-build projects are safety improvements that are designed to be installed rapidly, using materials like paint, flexible posts, rubber curbing, and prefabricated devices. These quick-build projects are different from traditional construction, that would involve concrete or asphalt.

Because quick builds go in faster and cost less than permanent infrastructure, the City can act on crash data quickly, test whether an improvement is working, and make adjustments before committing to a permanent design.

All projects in Greeley's SS4A program are quick-build installations.

Project locations were chosen based on data, not guesswork.

The City started by identifying streets and intersections with the highest number of fatal and serious injury crashes — a list known as the High Injury Network (HIN) and High Risk Node (HRN). These designations come from Greeley's Vision Zero Action Plan, completed in February 2025.

From there, a team of traffic engineers, City staff, police officers, school district representatives, and community members visited 128 locations across the city to take a closer look. They reviewed crash history, vehicle speeds, traffic volumes, nearby schools, and pedestrian and bike facilities. Based on that review, locations were recommended for safety improvements.

Some projects will affect on-street parking — but only where doing so directly improves safety.

In several corridors, removing or relocating parking is necessary to improve lane delineation, install bike lanes, or create clearer sight lines for drivers and pedestrians.

Where parking changes are part of a project, that will be clearly communicated to nearby residents and businesses in advance. The goal is never to remove parking for its own sake — it is always tied to a specific, documented safety need at that location.

These improvements are designed to reduce the number and severity of crashes at the targeted locations.

Specific expected benefits include 

• slower vehicle speeds
• shorter and more visible pedestrian crossings
• reduced conflict points between drivers and people on foot or bike
• clearer guidance for drivers through improved lane markings.

The safety improvements used in this program are not new — they have been tested across the country and proven to work. For example, the Federal Highway Administration has found that Rectangular Rapid Flashing Beacons (RRFBs) — the bright, rapidly flashing warning lights installed at crosswalks — can cut the risk of a pedestrian being struck by nearly half.

The City will monitor conditions before and after each improvement to measure real-world results.

Actually, that is exactly the goal — and it has a name: Vision Zero.

We adopted the Vision Zero framework in the Greeley on the Go Vision Zero Action Plan (February 2025). As part of that framework, we are committed to the goal of eliminating all traffic deaths and serious injuries on city streets.

Vision Zero is grounded in the idea that traffic deaths are not random accidents — they are predictable, preventable outcomes of road design and vehicle speeds that can be reduced through targeted action. The SS4A program is one major step toward that goal, but reaching zero will require sustained investment, ongoing monitoring, and continued partnership with the community over time.

A mini-roundabout works the same way as a full-sized roundabout — vehicles travel in one direction around a central island, yielding to traffic already in the circle — but it is much smaller and built using quick-build materials like rubber islands and paint rather than permanent concrete.

Because they are smaller, mini-roundabouts are designed for lower-speed neighborhood streets and intersections with less traffic. Full-sized roundabouts are built for busier arterial roads and require significant construction.

Both types eliminate the most dangerous type of crash — high-speed right-angle collisions — by replacing them with lower-speed, glancing-angle interactions.

One of the key advantages of quick-build infrastructure is that it is designed to be evaluated and adjusted.

We will monitor conditions at each project location before and after installation to measure changes in vehicle speeds, traffic patterns, and — over time — crash rates. If a specific improvement is not achieving its intended results, it can be modified, supplemented with additional countermeasures, or removed.

This flexibility is a core feature of the quick-build approach: it allows the City to learn from real-world results and continuously improve, rather than locking in a permanent design before knowing how it performs.
