Walk Above Black Canyon for Hoover Dam’s Best Free View
The Mike O’Callaghan–Pat Tillman Memorial Bridge carries Interstate 11 across the Colorado River between Nevada and Arizona. A pedestrian walkway along the bridge provides a dramatic elevated view of Hoover Dam, the river, Black Canyon, and the surrounding desert landscape.
Walking the bridge is a memorable option among the area’s free things to do near Las Vegas. No attraction ticket or tour reservation is required to use the outdoor pedestrian walkway during normal public access.
The bridge is about 1,900 feet long and rises approximately 890 feet above the Colorado River. The high viewpoint makes it especially impressive for photographers and engineering enthusiasts, but visitors who are uncomfortable with heights may prefer to stop near the entrance rather than cross the entire span.

What to Expect on the Bridge Walkway
The pedestrian approach begins on the Nevada side of the bridge. Visitors climb stairs or follow the longer paved ramp to reach the bridge plaza and walkway.
Once on the bridge, a tall concrete traffic barrier separates pedestrians from Interstate 11. A metal railing lines the canyon side, providing clear views toward Hoover Dam and down into Black Canyon.
The best dam view appears after walking out onto the span. Drivers crossing the bridge do not receive the same open view because the roadway barriers limit side visibility.
The bridge walkway is wide and level once visitors reach it, but the approach from the parking area involves an incline. The complete outing can require more walking than expected, particularly when crossing a large portion of the bridge and returning to the same parking area.
The Colorado River appears far below, and vehicles can create noticeable sound and vibration along the adjacent roadway. High protective barriers make the walkway safer, but they do not eliminate the sensation of standing hundreds of feet above the canyon.
A Landmark Colorado River Crossing
The bridge was constructed as the central feature of the Hoover Dam Bypass, which moved through traffic away from the narrow roadway across the top of Hoover Dam.
Construction of the overall bypass began in the 2000s, and the bridge opened to traffic in October 2010. Its concrete arch spans Black Canyon downstream from the dam while supporting a four-lane section of Interstate 11.
The project improved the highway connection between Nevada and Arizona, reduced the former traffic bottleneck at Hoover Dam, and allowed through vehicles to cross the Colorado River without entering the dam’s visitor and security area.
The Federal Highway Administration has recognized the bridge as a major concrete-arch engineering achievement. Visitors can review additional background through the Federal Highway Administration’s bridge dedication information.
Who Were Mike O’Callaghan and Pat Tillman?
Mike O’Callaghan
Mike O’Callaghan served as governor of Nevada from 1971 through 1979. He was also a teacher, journalist, public official, and decorated Korean War veteran whose career emphasized public and military service.
Pat Tillman
Pat Tillman played college football at Arizona State University and professional football for the Arizona Cardinals. Following the September 11 attacks, he left his NFL career and enlisted in the United States Army, later serving as an Army Ranger.
The bridge’s dual name recognizes two people closely associated with Nevada and Arizona whose lives became identified with public service, military service, and personal sacrifice.

How to Find the Memorial Bridge Walkway
From Las Vegas, take I-11 south through Boulder City toward Hoover Dam. Use Exit 2 and follow the signs for Hoover Dam Access Road.
At the traffic circle, take the third exit onto NV-172. Continue toward Hoover Dam and watch for signs identifying the Memorial Bridge Plaza or bridge-viewing area on the Nevada side.
The pedestrian walkway is not entered directly from the Interstate 11 travel lanes. Visitors must park in the designated viewing area and approach the bridge on foot.
The bridge plaza is separate from the Hoover Dam Visitor Center parking garage. Visitors who also plan to walk across the dam, take a tour, or enter the Visitor Center should continue along Hoover Dam Access Road after completing the bridge stop.
Traffic delays are common during weekends, holidays, summer travel periods, and special events. Check current Nevada road conditions for construction or temporary bridge-walkway closures.
Current Hoover Dam hours, security information, parking details, and official driving directions are available through the Bureau of Reclamation’s Hoover Dam visitor website.
Best Time for Views and Photos
Morning is usually the most comfortable time during warm months. Temperatures are lower, the parking area may be less crowded, and the sun begins illuminating the dam and canyon walls.
Late afternoon can provide attractive light across Black Canyon, but visitors should allow enough time to walk back before the public area closes. Do not begin a long bridge walk close to closing time.
Summer midday conditions can be dangerous because the exposed concrete walkway has almost no shade. During winter, the bridge can feel much colder than Boulder City or Las Vegas because of elevation and strong canyon winds.
For photographs, walk far enough onto the bridge to obtain an unobstructed view of Hoover Dam. Keep camera straps, hats, and loose belongings secure in windy conditions.
Tips Before You Go
- Check current hours: Hoover Dam’s outdoor public area is currently scheduled from 5:00 a.m. to 9:00 p.m., but special events, maintenance, security activity, and severe weather can change access.
- Bring water: There is no shade on most of the approach or bridge walkway.
- Use sun protection: Wear sunscreen, sunglasses, and a secure hat during daylight visits.
- Dress for wind: Conditions on the bridge can be considerably windier than in Las Vegas or Boulder City.
- Wear walking shoes: The paved approach includes an incline, and the bridge itself is approximately 1,900 feet long.
- Stay on the walkway: Do not climb barriers, sit on railings, enter roadway areas, or leave designated pedestrian routes.
- Follow posted rules: Current restrictions for bicycles, scooters, skating devices, animals, and other activities should be confirmed from signs at the bridge plaza.
- Supervise children: Keep children close on the approach, stairs, ramp, plaza, and bridge walkway.
- Prepare for heights: People with a strong fear of heights may be more comfortable viewing the bridge from the plaza.
- Secure loose items: Strong wind can carry away hats, papers, lightweight bags, and unsecured camera equipment.
- Do not fly a drone: Drones are prohibited on Hoover Dam property.
- Allow extra driving time: Security operations, holiday traffic, construction, and crowded parking areas may cause delays.
