Home » Guides » Missouri » Route 364 - Page Avenue Extension

The final nine miles of Missouri Route 364 were constructed at a cost of $118.2 million commencing in Spring 2013.1 This extended the freeway west from Mid Rivers Mall Drive at St. Peters to Interstate 64 & U.S. 40 at Lake St. Louis. Work was completed from west to east, with the portion from I-64/U.S. 40 east to Route K at O'Fallon opened October 4, 2014,4 and from Route K east to Mid Rivers Mall Drive on November 1, 2014.5 The final stretch of Page Avenue extension carries four lanes with a grassy median.

Planned since the 1970s, Route 364 (Page Avenue extension) first opened to traffic on December 13, 2003 between Interstate 270 at Maryland Heights to Heritage Landing and Jungs Station Road in St. Charles. Began in 1997, the $348 million segment included the Missouri River span (Veterans Memorial Bridge).2 The second phase extended the highway west to Mid Rivers Mall Drive with completion of that section on August 30, 2012.1 That included $19.6 million for a mile extension of Page Avenue to Woodstone Drive, where a new interchange was added to replace the signalized intersection of Missouri 94 at Harvester Road. This two-year element of road work started August 22, 2007.3
