This review is for the by pass bridge.To get to the by pass walkway u still have to go through the security ck point like if u were going to the dam,from vegas about a 1/2 mi past ck point, there is parking on the right to get to the walkway for the bridge. Their is a ramp and/or stairs u can use. The walk one way is about a mile from the parking lot to the far end of the bridge. The walk dead ends at the AZ side. The views are great. U can get some really nice shots of the dam. I guess if wanted nice shots of the by pass bridge u would have to b on the dam, dam . If u drive across the by pass bridge u won't have any view as the concrete walls are about 5 ft high, I drive a full size pic up and could not see anything . From what I can tell going to AZ , should b alot more conveniant .
