Cousins' family lived in 1960 era sub-division by Cave Springs exit, in St. Charles Co. Back in 60's was rural, and their neighborhood [West Clay & Sawyer] seemed like only houses for miles, though I was pre-teen. {Didn't see old part of St. Charles til 1972.}

Then, when there in '73, traffic on I-70 was heavy, and its bridge had potholes. By next visit in '78 was fully suburban, with Target, Venture and other shops at Cave Spgs. In 80's saw new St. Peters Mall and more development to US-40. And, the 270-70 interchange was modernized from cloverleaf. 90s-00s even more built up.

As someone said, was amazed at all the wide free/expressways & interchanges, but then Chicagoland doesn't have the room to expand as much.

Now, like to look at area on Google, and recently joined this site, and interesting to hear what's going on with roads, etc.

Do you remember if I-70 in St Charles County (specifically the area around Cave Springs you mentioned) was 4 lanes or 6 lanes back then? Based on the satellite image, with different pavement color and a narrow left shoulder (6 feet, opposed to the 10 feet required in interstate standards), I have a feeling that it was originally 4 lanes, and later widened to 6 in the inside. I could be wrong.

I-70 was 4 lanes back then, [late 60's]. Was clogged by 1972/73. By 1978, MO was building 2nd bridge, and then 70 was 6 lanes.

Why I-70 West of I-270 is not at least eight lanes the entire way to at least I-64 by now just blows my mind. I think I have seen that there are at least plans now to extend the six-lane portion to West of Wentzville Pkwy (that old railroad underpass has been needing work for over 20 years now). Of course, I-64 should also be six lanes to I-70 (I guess we should also be happy at least it is a full interstate that distance now, considering the memory of dealing with those stoplights).

I have driven past the interchange (no photos).  Heritage Crossing is 13A and MO 94 east is now 13B (formerly 13).

Congratulations MoDOT, you spent extra money replacing other signs that you didnít really need to by not calling it exit 12, and not matching with the WB exit for the same road.

That was quick, it's on GSV already.
Interesting seeing two signs go on a single side gantry. Normally (at least in Missouri), I only see a single sign on a side gantry, and if more than one is needed, then an overhead gantry is used instead.
