Interstate 070 East
Turning southward, I-70 spans Riverview Boulevard ahead of its transition to Bircher Boulevard. Riverview Boulevard carries Missouri 367 north from Bircher Boulevard west. The state highway runs 8.96 miles north to U.S. 67 (Lindbergh Boulevard). 04/13/13

Exit 244A consists of a split-diamond interchange with both Union Boulevard and Kingshighway.

U.S. 40 Alternate also traveled the boulevard at one point. 04/13/13
The Express Lanes split from the Interstate 70 mainline ahead of the Union Boulevard overpass. These lanes travel between the main roadways of I-70 for the next six miles to Broadway near Downtown.
Until December 2011, these lanes were reversible, serving inbound traffic during the morning and outbound traffic during the evening. Based upon traffic flow, MoDOT made the Express Lanes eastbound only. 04/13/13
The 1998-2003 reconstruction of Interstate 70 and the reversible lanes included the addition of gate at the Express Lane entrance. The gate was lowered when traffic along the reversible lanes flowed outbound to prevent wrong-way drivers. 04/13/13
Interstate 70 passes by Penrose Park and spans a Southern Pacific Railroad line on the quarter mile approach to Exit 245A. Exits 245A and 245B follow in succession to adjacent Bircher Boulevard, as the service road links Shreve Avenue at Penrose with Florissant Avenue at O'Fallon Park. 04/13/13
