West Valley City's Most Dangerous Intersections for Pedestrians and Cyclists

How the count was made: UDOT's signalized-intersection pedestrian and bicycle safety model lists 63 traffic signals inside West Valley City. For each of them we pulled every pedestrian- or bicycle-involved crash in UDOT's crash records that happened within 250 feet of the signal, the distance the Highway Safety Manual uses for intersection crashes, from January 1, 2018 through August 4, 2025. A crash near two signals is credited once, to the closer one. We call a crash serious or fatal when UDOT coded its severity as Fatal or Suspected Serious Injury.

Across those 63 signals the tally is 194 pedestrian crashes and 82 bicycle crashes. UDOT coded 16 of the pedestrian crashes and 6 of the bicycle crashes as fatal or suspected serious injury, or 8.2% and 7.3%. Forty-six of the signals, close to three in four, had at least one pedestrian crash. West Valley City has about 5% of the signals in the statewide model (63 of 1,263) and about 9% of the pedestrian crashes counted at them (194 of 2,105).

One Road, Half the Serious Pedestrian Crashes

Thirteen of the 63 signals sit on 3500 South (SR-171), roughly one in five. Those thirteen account for 75 of the city's 194 pedestrian crashes, nearly two in five, and 8 of the 16 that were serious or fatal, exactly half. Five of the top ten below are 3500 South crossings. They include its junction with Redwood Road, which has more pedestrian crashes than any signal in UDOT's statewide model, and 3600 West, where the 13 on record were topped at only four signals anywhere in Utah.

Redwood Road (SR-68) is the other half of the picture. Just four of the city's modeled signals are on it, yet together they logged 49 pedestrian crashes and 22 bicycle crashes. At 4100 South, the junction UDOT files under both West Valley City and Taylorsville, the busier road carries about 43,000 vehicles a day and the model estimates roughly 960 people cross on foot daily.

Ten Signals, Ranked by Pedestrian Crashes

Order follows the pedestrian crash count. Where signals tie, the one with more bicycle crashes comes first, then the one with more serious or fatal pedestrian crashes; five signals sit at five, and 4100 South & 5600 West (SR-172) misses the cut on that last tiebreaker. Daily pedestrian and vehicle figures are UDOT model estimates.

• 3500 South (SR-171) & Redwood Road (SR-68) — 23 pedestrian crashes, 1 serious or fatal; 9 bicycle crashes, 1 serious or fatal. No signal in Utah has more pedestrian crashes, and only two have more bicycle crashes. Two state routes meet here, with about 585 pedestrians a day and four bus stops nearby.
• 4100 South & Redwood Road (SR-68) — 19 pedestrian crashes, 1 serious or fatal; 6 bicycle crashes. Second in the state for pedestrian crashes. UDOT lists it under West Valley City and Taylorsville. Roughly 960 pedestrians a day.
• 3500 South (SR-171) & 3600 West — 13 pedestrian crashes, none coded serious or fatal; 2 bicycle crashes. The heaviest estimated foot traffic of any signal in the city, about 1,180 a day, plus four bus stops.
• 3500 South (SR-171) & 4800 West — 8 pedestrian crashes, 1 serious or fatal; no bicycle crashes. A three-legged junction with a school nearby and about 360 pedestrians a day.
• 4100 South & 4000 West — 6 pedestrian crashes and 1 bicycle crash, none serious or fatal. Five bus stops nearby, more than any other signal on this list.
• 3500 South (SR-171) & 5600 West (SR-172) — 6 pedestrian crashes, 1 serious or fatal; no bicycle crashes. Like the Redwood corner, a meeting of two state routes, here near a school, with about 692 pedestrians a day and about 40,500 vehicles on the busier road.
• 3100 South & 3200 West — 5 pedestrian crashes, 1 serious or fatal; 2 bicycle crashes, 1 serious or fatal. A school is nearby.
• 3100 South & Constitution Boulevard (2700 West) — 5 pedestrian crashes; 2 bicycle crashes, 1 serious or fatal. Near a school, with about 335 pedestrians a day.
• 3500 South (SR-171) & 6400 West — 5 pedestrian crashes, 2 of them serious or fatal, tied for the most at any West Valley City signal; 1 bicycle crash. Only about 163 pedestrians a day, the lightest estimated foot traffic in the top ten.
• Lehman Avenue (3590 South) at Valley Fair Mall & Constitution Boulevard (2700 West) — 5 pedestrian crashes, 1 serious or fatal; 1 bicycle crash. About 433 pedestrians a day at the signal serving the mall.

Read together, the ten have a shape. Six sit on 3500 South or Redwood Road, both state routes, and nine are ordinary four-way crossings. Between them they hold 95 of the city's 194 pedestrian crashes, just under half, and 8 of the 16 serious or fatal ones.

Where Bicycle Crashes Cluster

Bicycle crashes are fewer, 82 in all, but they lean toward the same road. The four Redwood Road signals account for 22 of them, more than a quarter: 9 at 3500 South, 6 at 4100 South and 5 at 3100 South. The six bicycle crashes coded serious or fatal were spread across six different signals, one apiece, so no single corner stands out for severity on a bike.

Foot Traffic Explains Only Part of the Ranking

UDOT's model also estimates how many people walk through each signal on a typical day. Busy crossings do tend to show up near the top, but the fit is loose. 3500 South & 3600 West has the heaviest estimated foot traffic in the city, about 1,180 a day, and ranks third. 3500 South & Redwood Road carries about half that, roughly 585, and ranks first.

The sharpest contrast is about three miles west. 3100 South & 4400 West is estimated at 584 pedestrians a day, nearly identical to the Redwood Road corner, and has no pedestrian or bicycle crash on record in the period. Vehicle volume is one difference: the busier road there carries about 7,000 vehicles a day, against about 34,500 at 3500 South and Redwood. The volumes are model estimates without a stated count date, so they sit beside the crash totals here rather than being divided into a rate.

Early Mornings and the Darker Months

West Valley City's pedestrian crashes start early. The 6 and 7 a.m. hours alone produced 32 of the 194, and the 6 to 9 a.m. block 40, or 20.6%, compared with 15.8% at signals statewide. Thursday was the heaviest day, with 45, nearly double Tuesday's 23. The season matters too: in the complete years 2018 through 2024, September through December accounted for 77 of 178 pedestrian crashes, 43.3%, while July had the fewest, 8. Darkness covered 75 crashes, 38.7%, somewhat above the statewide 34.1%. Severity, though, stayed comparatively low in every part of the day; 16 of the 194 pedestrian crashes, 8.2%, were serious or fatal, about half the statewide rate.

Hit and Run, for Walkers and Riders Alike

Drivers left the scene in 42 of the city's 194 pedestrian crashes, 21.6%, and in 20 of its 82 bicycle crashes, 24.4%. That bicycle figure is the highest of any Utah city with at least 20 bicycle crashes at its signals, and more than double the statewide 10.0%. Only 1 of the hit-and-run pedestrian crashes was recorded as serious or fatal. Teen drivers appear in 19 pedestrian crashes, 3 of them serious or fatal, and the city's 2 impaired-driver pedestrian crashes were both serious or fatal.

For a cyclist, a hit and run works much as it does for someone on foot. The rider's own uninsured motorist coverage can respond, because the law treats an unidentified vehicle that left the scene as uninsured (Utah Code § 31A-22-305(2)(b)), and a relative who lives in the same household as the named insured is a covered person under the same section (§ 31A-22-305(1)(c)). Write down whatever you can of the vehicle, a partial plate, a color, the direction it went, and get the report number; those details are what such a claim is built on.

The Faster Western End of 3500 South

3500 South (SR-171) changes character across the city. Through the eight signals where it is posted at 40 mph, including Redwood Road and 3600 West, it recorded 55 pedestrian crashes, 4 of them serious or fatal. Through the four signals farther west where it is posted at 45 mph, from 4800 West to 6400 West, it recorded 19, but just as many, 4, were serious or fatal. Redwood Road (SR-68) is posted at 40 mph at all four of its signals in the city. Of the ten signals on the list above, five top out at 40 mph, three sit on the 45 mph stretch of 3500 South and two are 35 mph crossings on 3100 South. UDOT's state-route sidewalk inventory notes absent or discontinuous sidewalk within about 500 feet of 3500 South and 5600 West. These are current posted limits, not the speed of any vehicle involved.

What These Counts Leave Out

A crash is included only if it happened within 250 feet of one of the 63 signals. Someone struck mid-block, at an unsignalized crosswalk, in a parking lot or at a driveway is not in these numbers. The figures count crashes, not people; one crash can involve more than one pedestrian. And nothing in UDOT's records decides who was at fault.

If a West Valley City Intersection Is Where You Were Hit

What happened at that corner before your collision is discoverable, and it matters. A pattern of earlier strikes speaks to whether the danger was already known. The geometry, markings, signal phasing and lighting speak to whether the crossing itself played a part. Both feed into what an insurer is willing to pay. UDOT's crash data is open to the public, and the city and the state hold the engineering records behind it. Our West Valley City pedestrian accident and bicyclist accident pages set out how those claims run, and the statewide guides cover how fault is proven, how to file a PIP claim and the deadline to bring a case.

What a Claim Can Cover

• Out-of-pocket losses: ambulance and hospital bills, surgery, physical therapy, wages missed during recovery, and diminished earning power if the injury proves permanent.
• Human losses: physical pain, and the everyday independence that comes with being able to walk or ride safely through your own neighborhood.
• Long-term needs: revision surgery, treatment that continues indefinitely, and assistance at home when recovery stops short of full.

Sources and Method

Crash counts come from UDOT's crash records: pedestrian- and bicycle-involved crashes within 250 feet of each signal (the Highway Safety Manual's intersection distance), each credited to the nearest signal, from January 1, 2018 through August 4, 2025. Serious or fatal means UDOT severity Fatal or Suspected Serious Injury. The list of signals, the pedestrian and bicycle volumes, traffic volumes, nearby schools, bus stops and lighting come from UDOT's signalized-intersection pedestrian and bicycle safety model. Statewide comparisons apply the same count to all 1,263 signals in that model. The hour, month, lighting and hit-and-run, teen-driver and impairment figures use the same UDOT crash records, as coded by the responding officer, and the monthly comparison is limited to the complete years 2018 through 2024. Posted limits are current: UDOT's 2026 state-route speed limits and UGRC's Utah Roads estimates on city streets; the sidewalk note comes from UDOT's state-route inventory.
