Title: Basis for Mile Markers on Texas 130
Post by: DevalDragon on November 16, 2013, 07:02:00 PM
Anybody know what they (TxDOT) is using for a basis for the mile markers on Texas 130? They count up north to south; I-35 in Georgetown is 417 and 130/45 and US 183 is 458, and the southern extension to I 10 has no exit numbers at all.

Apparently Georgetown is 407 miles south of the north edge of the Panhandle (36 30′ N).
