El Paso: bids opened for IH-10 widening

<< < (5/5)

DJStephens:
   There is currently activity in the median between Vinton (Exit 2) to just N of Redd Road (Exit (9).  Appears to be work to close the median, by completely rebuilding all arroyo crossings with bridges that have greater spans, than the originals, that had multiple short spans.  In short, complete replacements of all arroyo crossings, in phases.   So the bridges will be "half finished" and then traffic (two lanes each direction, cattle chutes, no shoulders) will be shifted inwards, and then demolition and replacement of arroyo crossings will continue on the outside lanes. This complexity and expense, of the crossings, probably explains much of the total cost of this operation, and the length of the total project.   That, and the what believe will be conversion to all concrete pavements.   
   Am holding breath to see if they correctly bring down the "crest" in the 10 mainlines, S of Artcraft.  (MP 8) Am guessing they will not, and there will be a similar situation to what happened in the mid-late nineties on the E side, (MP 31) where a "humped" up mainline was left that way, instead of being properly "flattened" for greater sight lines.   They even put continuous reinforced concrete pavement over the hump.  At this point it doesn't look good.

I've never heard of concrete barriers being colloquially referred to as "cattle chutes" before. But anyways, yes those lanes are very narrow. When you are passing a truck, there's not more than a meter between your driver side mirror and the concrete barrier.

I also noticed that they filled in the rumble strips just north of Redd where the project lane shifts start/end. It was very jarring to drivers to have to drive over them at the start/end of the construction zone. It probably caused a lot of drivers to slam on the brakes.

I looked on GSV but didn't see any "humped" up mainlines near MP 31. At least nothing as noticeable and egregious as the hill between Artcraft and Redd Rd. It's silly that TXDOT left that hill when they could have graded it and elevated the frontage roads more, which dip pretty low near Helen of Troy Drive and Montoya Lane.

The term refers to the lanes between the barriers. Usually reserved for a one-lane section because if someone breaks down or hits barrier, the entire lane is blocked. 2 narrow lanes without shoulders can also merit the appellation.
