There are no turn lanes for acceleration or deceleration at those intersections. Traffic has to slow down from going 80mph or faster down to nothing to make any of those turns. From what I've seen via Street View in Google Earth those intersections are poorly signed.

The other danger is the element of surprise to motorists, cruising along at 80mph not expecting any at grade turns with possible crossing or turning traffic. Plenty of drivers are distracted and inattentive. On a very long drive, like the trek between El Paso and San Antonio one can get a little hypnotized by both the length and desolation of the trip. They might not be perfectly ready to have to suddenly hit the breaks for cars ahead slowing to make a right or left turn, or other drivers turning onto the road in front of them.

I think the short stretches of frontage roads for at grade right turns and no crossing traffic across Interstate lanes is a good alternative. It's not going to hurt a rural farmer or oil field work to drive a mile or two down the road to the next bridge to get across to the other side of the highway.

What's the traffic like on that part of I-10?  I imagine it's easily a LOS A facility.  If a farm truck slows down to turn off the freeway ahead of you, just change lanes to pass.  You probably won't even have to disengage your cruise control.

A 40 mph farm truck negotiating a turn-off on a freeway posted for 75 or 80 mph??? Seriously?? By the time you do disengage your cruise control you're dead.  Unless you have proper warning signals for such turn-offs, better to have frontage roads or back roads for that.

Maybe pay attention while you're driving. It's not like you're going to go over a hill and randomly come upon turning traffic. All of the areas with direct freeway access are flat as a board. You'll see that truck at least a mile before you get to it and have plenty of time to move over.

So...you're saying that through traffic on a freeway designed for 70 mph should cede to the shoulder for turning traffic onto a direct crossover? In that case, it's no longer a freeway. Would you recommend that everywhere for all Interstate-grade freeways to have direct access crossovers? NO.

I'm taking about traffic on RIROs going into the shoulder to turn. Not other traffic going on the shoulder.

OK...for RIRO's, that would be acceptable, although I still would prefer a dedicated turning lane rather than using the shoulder, just to free up the mainlaines.

My real issue is with *left-turn* at-grade crossovers used for direct access on otherwise freeway facilities. HELL TO THE NO on that.
