Florida State Road 202

SR 202 begins at US 1 (Philips Highway) and starts its run east as a divided, six lane surface street, going east towards I-95 and becoming a freeway, passing through mostly marshland as it heads east towards exits including SR 115 (Southside Boulevard) and I-295 (East beltway), before ending at SR A1A, just west of the Atlantic coastline.[3]

The expressway is named for J. Turner Butler, a well-known Jacksonville attorney and Florida legislator who was instrumental in advancing various transportation projects in the region and the establishment of the Jacksonville Expressway Authority. J.T.B. was a toll road until 1988, when the JTA removed all the toll-collection facilities in Jacksonville.

When J.T.B. initially opened, it was described by locals as "the road to nowhere". The moniker has diminished over the years as increased growth on Jacksonville's Southside area, as well as at the beaches and in St. Johns County has transformed the road into a major commuter route. Because of the heavy traffic on J.T.B. and projected continued growth in the Jacksonville area, the Florida Department of Transportation, in the early 2000s, conducted a study on making long-term improvements to J.T.B. The study results recommended widening the road and designating "inside" express lanes with limited on and off points along the route, surrounded by additional "outside" local lanes, albeit at a considerable cost. While this was not implemented, most of the highway between I-95 and the Intracoastal Waterway was widened to three to five lanes in each direction in the early-to-mid 2000s.

The Arthur Sollee bridge spans the Intracoastal Waterway and is known by locals as the "Whubba Whubba" bridge, due to defect in construction that make for an amusing bouncy ride on the eastbound side of the roadway.

Between the summer of 2005 and December 24, 2008, an $80 million freeway-to-freeway "whirlpool" style interchange was constructed at the interchange of J.T.B. and I-295, with the final piece to open being a flyover ramp from J.T.B. east to I-295 north.

Until late 2017, access to J.T.B eastbound from I-95 southbound was handled through a traffic-signaled intersection that was located near the highway's western end. This configuration created significant congestion during rush-hours, causing traffic to back-up onto I-95. To alleviate this situation, a flyover was constructed during the mid-2010s from I-95 southbound to J.T.B eastbound, along with other improvements to the I-95/J.T.B/Belfort Road/Salisbury Road interchanges. Under this new configuration, the signaled intersection remained in place but is now only used to provide access from I-95 to the Belfort/Salisbury/Southpoint commercial area since the new flyover merges into J.T.B eastbound past the existing off-ramps in the Belfort/Salisbury interchange.

As of 2020, the FDOT is constructing capacity improvements to the perennially-congested Gate Parkway interchange (which provides access to St. Johns Town Center). The FDOT is also proposing upgrading the San Pablo Road interchange to a diverging diamond interchange (with right-in/right-out access to Mayo Clinic).[4] In the future, the traffic light for eastbound J.T.B traffic headed to northbound Kernan Blvd. is excepted to be replaced with a loop ramp to be built in the southeast quadrant of the interchange.

The entire route is in Duval County. All exits are unnumbered.
