I went ahead and connected it, and now I'm going to get on my soap box here for a second....
*grabs soap box and stands on it*
It irks the shit out of me when the service roads are labeled the same as the highway. The highway shields will actually move to the service roads (yes, I've seen the entire service road with the I-35 shield from Waco to Austin). I've been going around and adding "service rd" or "frontage rd" to the ends of the names of the those roads, so there won't be two US-75 or two US-69s. It could also confuse a driver who's not used to service roads. If the driver is instructed to "exit to Exit 74, Texas Travel Center, then stay to the left on US Hwy 75" after just getting off of 75, the driver could be confused as to what's going on.
