Parts of I-255 near St. Louis to close for 10 months starting this weekend

IDOT says completely closing I-255, between Interstate 64 and Interstate 55/70, to fix it will save money, but will commuters wind up paying with their time?

COLLINSVILLE, (KMOX) - Metro East drivers, find your alternate routes now because I-255 is closing completely for major construction, first for the stretch between 55/70 and 64, that starts this Saturday. 

The overall project consists of rehabilitating and resurfacing approximately 7 miles of I-255 from Collinsville Road to Illinois 15 in two sections separated by I-64, with significant bridge repairs, safety improvements and drainage upgrades. Once the section north of I-64 is finished this summer, construction will shift to the section between I-64 and Illinois 15.

Altogether, the construction is expected to take 10 months. The North Work Zone and South Work Zone is expected to be closed for five months each. 

I-255 Detour Routes

While Interstates 55/70 and 64 will be the marked detour, depending on direction of travel, the following alternate routes are recommended: Illinois 3, Illinois 15, Illinois 157, Illinois 158, Illinois 159 and Illinois 161. Public transportation and traveling during off-peak hours are encouraged as well, says IDOT.
