I-240: OK 118?

[bugo]

This excerpt from the 1956 Oklahoma County Control Section Map published by the Oklahoma Department of Highways shows what became I-240 as a control section of a route called 118. The map seems to indicate that part of what is now I-240 was open east of where I-35 is now. Was this section of I-240 opened before the other sections that are shown as P&S? Was this road ever signed as an OK 118?

That part of 240 sits on top of SE 74th Street but I don't recall that ever being a state highway.  Since this was hand-drawn, maybe it's a mistake.

I don't think it's a mistake–114 and 119 were both commissioned in 1957 (according to uncited information on Wikipedia), so the 118 number fits as being added as part of a block of designations from that time period.

I don't know that 118 was necessarily signed–if I remember correctly, only the part of I-240 west of I-35 was part of the original 1956 Interstate system, and the part east of I-35 was added later. That would explain why I-240 was P&S (it was actually funded). It could be that ODOT had planned to extend I-240 east, and 118 was a placeholder designation until that could be added in a later Interstate funding bill.

You are correct about the eastern part of I-240. IIRC, it was added in the late 60's.
