BUMP - to share this article covering an update on I-11 construction:
Boulder City Bypass taking shape, Las Vegas Review Journal, 7/30/2016 (includes several construction photos).
Now more than a year into construction, concrete bridges are taking shape along the 15-mile stretch of dirt road that’s being transformed into Interstate 11. Builders say the project is on pace to open by fall 2018.
When completed, the four-lane highway is expected to reduce travel times up to 30 minutes between Henderson’s southern border and the O’Callaghan-Tillman Bridge downstream from Hoover Dam, all while looping past Boulder City, a small town with roughly 15,000 residents.
There's also this little tidbit about Railroad Pass:
Nearby, crews are also building a 360-foot-long steel truss bridge over I-11, aimed at reconnecting the railroad tracks between Henderson and Boulder City. The transportation department paved over a section of the tracks at U.S. Highway 93 near Railroad Pass in 1998, which was considered dangerous at the time, Illia said.
I've always thought it interesting that the railroad crossing signals and signs are still there (marked as exempt), but there's no tracks. I'm guessing with the I-515 freeway extension terminating just north of here by 1995-96 prompting travel closer to freeway speeds, having a railroad crossing wasn't a good idea (especially if buses and hazardous cargo was still forced to stop at the tracks). The article goes further to state that Boulder City is looking to make use of the reconnected RR spur for tourism purposes.
