July 24, 2019: This oversized US 6 shield was how the DOT initially signed US 6’s reroute onto I-80 on the east end of Council Bluffs. Straight ahead was IA 906, aka Kanesville Boulevard in the city.
The Iowa Department of Transportation turned IA 906 over to the city of Council Bluffs at its meeting last week.
The unsigned route was what had been US 6 from downtown Council Bluffs to I-80. The state turned over US 6 west of downtown, aka West Broadway, in 2016, although the exact date became a bit fungible. (The official route description says May 16. My blog post three weeks before that thought it would be May 1. Signs changed later.) Around the same time, but not all at the same time, the state turned over the entirety of IA 192.
The Kanesville Boulevard section of US 6 became IA 906 as US 6 was rerouted onto I-29 and I-80 to bypass Council Bluffs. Technically, US 6 follows I-29 only from I-480 to the east I-29/80 split (in the local lanes), and then shifts onto I-80 heading northeast.
On the other side of Council Bluffs, a DOT press release says that new lanes on I-29 are opening, requiring lane closures. The restriping will be complete Tuesday morning. The interstate has been detoured onto the newly built north-south frontage roads that intersect West Broadway.
