https://github.com/TravelMapping/HighwayData/pull/8229https://github.com/TravelMapping/HighwayData/pull/8230https://github.com/TravelMapping/HighwayData/pull/8231This ties up some loose ends, from my prolonged development of the usaca system which was activated in 2022. I-10BL in Blythe, and I-40BL in Needles, were carried over from CHM unchanged. Since then, signage was changed on I-10 to move the east end of the Blythe business loop one exit to the west (as neroute2 noted in his peer review of usaca, and I later confirmed that in a field check, which also didn't confirm hints in Google Maps that I-10BL extended east to exit 243). I also spotted a faded I-40BL route marker at the intersection of Broadway and L St., two blocks north of where CHM had the Needles BL turning west to I-40 on J St. BL signage is scarce in both cities (only two or three BL signs in each), but it is enough to indicate that the east endpoint of I-10BL and the west endpoint of I-40BL each were off by one exit.
