Best I can remember they were under Commercial Zone requirements as never accessed interstate, went by Axle Weights, 18 steer, 20 each dual wheel axle but full up the best they pulled from Westlake or the MO River Sand Plant on MO Bottom RD were around total 167,000 gross.  IIRC they could get close to 78,000 just for Truck Gross weight.

Gateway used to be where the Maryland Heights City hall currently sits, all gone to history now.  Was there when the 1977 R Series tri-drive with 26 yard bed was delivered, brand new tandem Joe Dog fifth wheel unit on a 40 ton Pintle, next stop was over to Fruehauf and picked up the 38' Tri-axle frame style curved corner dump trailer.  Was a hoss!!  Can actually get more on single trucks now with less hassle.

I worked at Mack STL on Chouteau in 1977, Herb Talley was my Foreman taught me so much in a short time.  Wish had pictures of the old Gateway Readymix three drivers dump two axle Joe Dog with the tri axle dump trailer that used to run from Maryland Heights to West Lake Quarry and back.  Average gross across Earth City Expressway was 167,000 lbs.

Worked at Mack Truck STL back in 1977, dealt with the Old Dogs until gave up mechanic in 98 as had gone thru a change of profession in 96 and could no longer do both.  Miss the old Bulldogs.
