MoDOT Set to Build Tower Grove/I-64 Interchange

MoDOT is getting ready to begin major work on I-64 between Kingshighway and Sarah. The project is essentially a continuation of the I-64 rebuild that closed segments of the highway between Spoede and Kingshighway in 2008 and 2009. Environmental studies for that project looked at rebuilding I-64 from Spoede to Sarah, but cost considerations forced MoDOT to delay work on the segment east of Kingshighway until next year.

The I-64 project:

replace the Taylor, Newstead, Tower Grove, and Boyle bridges over I-64

add a westbound entry ramp to westbound exit ramp at Boyle

lower I-64 by as much as 3 feet between Taylor and Newstead to improve sight distances

raise Newstead 6 feet to accommodate exit ramp passing underneath

create roundabout at intersection of Tower Grove Avenue and I-64 ramp
