Lolol. ^^^^^^^^^^
What will really make you LOL is that ALL of the On-Ramps to The Old Freeway, former Interstate 10 down in South Phoenix Buckeye Road-ish Area 19th Ave On Ramp, 7th Ave On Ramp, 7th Street....(is there an On Ramp at 16th Street?!? if so then that one too) are like what OP Describes. just without the Orange Cones.
They do have some what of an "Entry Lane", not very much though just enuff to make you know "Welcome To The Thunderdome" Tina Turner shit plays in the background at each meeting over the last 26 Years ADOT have met and had to sit thru Power Point Presentations of the problem, eventually deciding ain't a damn thing can be done about it. "Is What It Is."
Or what it was. That exists still today as we have thousands more vehicles vying to enter via On Ramps designed for a totally different time. Naturally theres Trucking Companies down there.
1950's architecture lol. I don't know The Exact date but man its Wild Down There.
Was there any Entry Lane at all? fightgood? After the abbreviated On Ramp? Is there any SHOULDER (area where Emergency Pull-Off can be done)...after that On ramp?
