U.S. 90 primarily serves local traffic throughout the majority of its routing in Florida due to the close proximity to Interstate 10. The route overtook the Old Spanish Trail when it was designated, with portions of U.S. 90 today retaining the name or closely paralleling the old roadway.

Despite the shift of through traffic to Interstate 10, many sections of U.S. 90 carry four overall lanes in Florida, both as commuter routes or as the main route between cities and towns. The stretch between north Pensacola and Milton for instance carries four lanes and is heavily developed to serve bedroom communities for Pensacola and Whiting Field Naval Air Station. The same can be said about U.S. 90 leading east from Tallahassee along Mahan Drive as suburban growth adds traffic. Within Jacksonville, U.S. 90 gains importance as a through route along Beach Boulevard between Downtown and Jacksonville Beach.

U.S. 90 (Beach Boulevard) was expanded and improved with medians, between St. Johns Bluff Road and Florida Community College at Huffman Road in Jacksonville, as part of a $2.6 million project starting in summer 1996.1 Further east, an overpass was added for Kernan Boulevard above U.S. 90. Construction was undertaken along side a $28.6 million expansion of Kernan Boulevard south from SR 10 to Glen Kernan Parkway. The $43.1 million urban diamond interchange opened to traffic at the end of March 2009.2 Widening of Beach Boulevard east from Hodges Boulevard to San Pablo Boulevard followed to early 2012.3

This 1948 map shows that a second U.S. 90 Alternate may have been signed along Scenic Highway between Pensacola and the Ferry Pass area as a temporary designation with the U.S. 90 mainline taking Davis Highway along what is now Florida 291.

An old alignment of U.S. 90 remains in use as a "service road" alongside the Perdido River bridge approach in western Escambia County. Named Ruby's Fish Camp Road, the former U.S. 90 retains original concrete and serves two homes before dead ending. Photos taken 02/01/06.
Marlane Drive ties into U.S. 90 (Mobile Highway) near Bellview as a former county road. Cerry Road (unsigned County Road 296A) leads east from Florida 173 (Blue Angel Parkway) to merge with Marlane Drive, old County Road 341, ahead of Mobile Highway. The traffic signals pictured here were replaced by mast arm assemblies. Photo taken 02/01/06.
Blue U.S. 90 shield that was posted on 17th Avenue northbound at Cervantes Street. This was the final colored U.S. marker in the city of Pensacola, lasting until at least April 2002.
Initially replaced by a standard black and white U.S. 90 shield, this assembly was eventually swapped out with a regulatory turn lane sign. Photo taken 08/27/99.
