So I ended up staying up late and sifting through this afterall.
Delaware proposed redesignating U.S. 202 from I-95 at Exit 8, 1.31 miles north to the original end of SR 141 at Fairfax as temporary I-195 in 1978.
When the section is rebuilt to proper standards we will request permanent designation of I-195.
The following year Delaware recommended eliminating Temporary I-195:
This section is only 1.31 mile and serves mainly short trip, local orientated traffic, and designation of temporary I-195 needs to be eliminated to avoid traffic confusion.
There's a number of applications from Delaware also for renumbering I-95 as I-395/595 before settling for I-895 during the major widening/reconstruction project through Wilmington.
For Florida, there was a request to extend U.S. 431 south in 1961 from Dothan to Panama City Beach. The route was proposed along SR 77, SR 277 and SR 79 south to U.S. 98. It was denied because of redundancy with U.S. 231 and it not being the most direct route, etc via AASHO's point scoring system.
Interstate 195 was originally submitted on August 8, 1958 for the "Bayshore Connector". It was deleted and 195 reassigned to the current route between Miami and Miami Beach in 1959.
Interstate 220 in Jackson, Mississippi was originally referenced as Route A20
Interstate 420 in Monroe, Louisiana was approved in 1958, as was the full I-410 loop in Baton Rouge.
AASHO did question whether the proposals for I-10/610 in New Orleans, as to whether they should be reversed.
The route carrying the major traffic stream should be allotted the two digit number and I am sure that you have considered this matter. However, Route 10 seems to be rather circuitous.
The Louisiana Department of Highways responded on September 3, 1958:
...concluded that the two digit number should be assigned to the route indicated in our submission of July 25, since this routing will carry the vast majority of the Interstate traffic entering the city of New Orleans. Furthermore, the section showing numbered as 610 will not be constructed in the early years of the program, and for continuity of routing, the proposal as submitted by this office is believed to be appropriate.
The Texas urban submissions in 1958 outlined:
- "Interstate Highway F 20" - IH 820 as a three quarter loop missing the NW quadrant
- "Interstate Highway H 45" - IH 610 without the portion between IH 45 and IH 10 to the east
- "Interstate Highway S 10" - IH 410 without the segment between IH 10 and IH 35 to the north.
- "Interstate Highway D 35E" - IH 635 was the same.
Texas initially outlined IH 20 as overlapping with IH 10 west all the way to El Paso.
In view of the instructions in Guide Number 6 in Purpose and Policy of Marking for the Interstate System, we are wondering if Interstate 20 in Texas should be considered terminated at its junction with U.S. 290 which is 40 miles west of Pecos, or should it continue in conjunction with Interstate 10 to a major control point, the city of El Paso.
A circumferential route around Texarkana was recommended for approval in November 1958. No number was assigned.
The alignment of IH 20 through Dallas/Fort Worth was outlined in 1958 as following what is now IH 30 east to IH 35W, then US 277 southeast to IH 820 and then the present alignment east into Dallas. Within Dallas, IH 20 followed US 67 northeast to an overlap with IH 35E to Downtown, and then IH 30 and US 80.
