Route 364, known locally as the Page Avenue Extension , the Page Avenue Freeway, or simply the Page Expressway, is a freeway that connects St. Louis County in Maryland Heights with St. Charles County in Lake St. Louis via the Veterans Memorial Bridge over the Missouri River. The highway is a designated auxiliary state route of I-64.
The current termini are at an interchange with I-270 to the east and at the intersection of I-64/US-40/US-61 to the west. The west end of the freeway was marked at Route 94 and Mid Rivers Mall Drive/Pitman Hill Rd. until November 2, 2014, when the Phase III expansion was opened.
The opening of the freeway increased the number of lanes across the Missouri River in the St. Louis metropolitan area from 23 to 33. It provides an alternate route to the Daniel Boone Bridge, Blanchette Memorial Bridge, and Discovery Bridge crossings.
