I noticed that the system isn't (wasn't) giving me credit for US 77 between I-35(501) and I-35(504). Problem seems to be that there's no I-35(503) waypoint listed for US 77 and so the system thinks US 77 is leaving I-35Gai for those three miles or so. I just drove it and confirmed that there's no divergence in that section. Adding an I-35(503) waypoint to the US77 file should rectify the issue. Thanks.
