Muscatine highway chronology

These maps show the highway evolution in the city of Muscatine and the immediate area. US highways are in red, state highways in purple, business routes in green, and four-lane highways in thicker lines. The thick blue line is the Mississippi River.

NOTE: At this time, the toll bridge did not have an assigned highway number. It goes over Front Street. The traffic flow was likely arranged such that Illinois-bound traffic would not have to make a left turn onto the bridge, instead turning from (either direction of) Front onto Cedar, then right on 2nd, then right onto the bridge.
End 38: Bridge
Northbound Park Avenue: Eastbound 2, northbound 20 and 38

August 18, 1924: IA 20 placed on new riverside alignment east of Muscatine to Davenport
January 6, 1925: IA 38 truncated to IA 2 junction, which at this time is north of the city
October 16, 1926: US 61 replaces IA 20; IA 2 truncated at Grandview (south junction US 61); IA 22 replaces IA 2 east of Muscatine

NOTE: Illinois proposed a state highway running west from Taylor Ridge IL to Muscatine in 1928 as part of a $100 million statewide construction bond issue. It was completed by the time of the 1930 Illinois map.
End 38: Junction IA 22
Northbound Park Avenue north of Washington Street: Eastbound 22

January 7, 1931: IA 2 re-extended to Muscatine
July 8, 1931: IA 22 extended westward
Before 1936: IA 38 re-extended to downtown Muscatine

End 38: Bridge
Northbound Park Avenue north of Washington Street: Eastbound 22, northbound 38

Sometime between 1938 and 1943: IA 22 realigned onto Cedar Street
February 1, 1939: IA 92 replaces IA 2 and IL 84

End 38: Bridge
Northbound Park Avenue north of Washington Street: Eastbound 22, northbound 38

June 1-October 12, 1956: Bridge closed
October 23, 1958: US 61 and IA 22 swap places east of Muscatine
January 1, 1969: IA 38 re-truncated to Y intersection at US 61
December 2, 1972: New Mississippi River bridge opens
Unknown: Front Street renamed Mississippi Drive
Unknown: New IA 38 bridge over Mad Creek leaves behind old segment called IA 953

End 38: Junction US 61
Northbound Park Avenue north of Washington Street: Northbound 61

1980: IA 953 turned over
December 12, 1984: US 61 bypass opens. You would think that 22 and 38 would have been changed at the same time, but records indicate differently. The state of the roads in 1985, below, was a short-lived deal.

NOTE: The 1974 Muscatine inset on the state map clearly shows 61 using Cedar to transition to 2nd...and then the inset disappears for two decades. Maps through the early '00s don't show a switch to Mulberry, but aerial photos from 1994 show that the change happened before then.
End 38: Junction US 61
Northbound Park Avenue north of Washington Street: Northbound Business 61, secret IA 922

1986: IA 22 rerouted onto bypass, IA 38 re-extended south to new bridge; small segment of 22 between bypass and city limits becomes IA 917
July 1, 1987: Bridge becomes toll-free
November 2000: US 61 opens to four lanes northeast of Muscatine

End 38: Bridge (Junction IA 92)
Northbound Park Avenue north of Washington Street: Northbound Business 61/IA 38, westbound IA 22

July 2002: US 61/IA 92 opens to four lanes southwest of Muscatine
July 1, 2003: IA 917 and IA 421 (short segment of 61 left behind when four-lane opened) turned over to county
October 22, 2008: Hershey Avenue (County Road G28) interchange opens on bypass, halfway between IA 22 and 92 (not shown)
Fall 2014 (officially July 1): IA 92 removed from Grandview Avenue/Mississippi Drive and put on bypass with US 61 and IA 38; IA 38's south end does not change

End 38: Bridge (Junction IA 92)
Northbound Park Avenue north of Washington Street: Northbound Business 61/IA 38, westbound IA 22/92
