State Road 113 (SR 113; also known as Southside Connector) is a 2.770-mile-long (4.458 km) state road. The freeway travels almost due north–south entirely within the city limits of Jacksonville, in Duval County.
SR 113 begins at an interchange with SR 115 (Southside Boulevard) just north of SR 10 (Atlantic Boulevard). It heads northeast and travels along the west edge of Regency Square Mall. Northbound, it has an interchange with Regency Square Boulevard North and then curves to the north to an interchange with Tredinick Parkway. On the southbound side, the two exits are combined. After that, there is an interchange with SR 116 (Merrill Road) east, which leads to an interchange with Interstate 295 (I-295, Jacksonville East Beltway) south. Almost immediately afterward, the freeway curves to the northwest and feeds into I-295 north.
