Thru Traffic

[huskeroadgeek]

A 2nd to the thread above.  In my childhood day (1st generation interstation construction), I saw "Thru Traffic" overhead signs all over the place.  I think control cities on "pull-through" signs came late 60's or early 70's.

Control cities have been around longer than that in some areas. I've seen early-mid 60s pictures of control cities on "pull through" signs.

I'd say about 1955 is when they started showing up in California - before that, it was the name of the freeway that was used.

On spurs as well, for example in California on I-210 westbound San Fernando and Sacramento, and on I-210 Eastbound Redlands and Palm Springs.

IIRC, Sacramento is presently only I-210's westbound control city starting in Sunland or so.

San Bernardino is the primary eastbound control city after Pasadena if I'm not mistaken.

Sacramento does show up on Mileage signs on 210 westbound once your out of Pasadena. 
Yes on 210 Eastbound San Bernardino is the control city after Pasadena.  But what I don't understand is that then Redlands and Mtn Resorts is the control point.  i always thought that Palm Springs should show up seeing how its the next main city along the 10 east.

Is Palm Springs ever used as a control on I-10 as opposed to Indio or "other desert cities?"

Palm Springs is used on a pull through sign at the 215/10 jct.  It says Redlands, Palm Springs.  Also Palm Springs appears as the control city on a couple of mileage signs on the 10 east.  60 East only uses Indio.

Another Texas highway uses "Thru Traffic" as its control city: westbound President George Bush Turnpike at its junction with I-35E.
