IV. Travel Time and Congestion
The study area is intersected by eight major roadways that form the primary roadway network serving the South County area. Major east-west corridors in the study area are Gibsonton Drive/Boyette Road, Symmes Road, Big Bend Road/Old Big Bend Road, 19 th Avenue NE, and State Road 674/College Boulevard/Sun City Center Boulevard. Major north-south corridors in the study area are US-41, I-75, and US-301. Single occupancy vehicle dependence is evident in South County where, according to 2013- 2017 American Community Survey (ACS) estimates, more than 80 percent of commuters drive to work alone. Wimauma is the only exception to this trend; approximately 70% of Wimauma commuters drive alone and more than 20% carpool. Wimauma also has the highest proportions
of households with income below poverty level (50% or more). Generally, the median income in the study area is between $50,000 and $74,999. Residents of Apollo Beach (10%) and Sun City Center (9.4%) were most likely to work at home, and also have the highest median age in South County of 45 years and 72 years respectively. Much of the trip making in these areas was also internal to the community.
Single occupancy vehicle dependence is evident in South County, where more than 80 percent of commuters drive to work alone. Only 1.5% or fewer use public transportation.
The Hillsborough MPO 2018 State of the System Report uses a map of user-reported traffic congestion to show congestion hotspots during the morning peak hours for commuters (between 6 am – 9 am) (Figure 12). Hotspots (shown in purple) in the study area are most visible along US 41, I-75, Gibsonton Drive/Boyette Road, and Big Bend Road. The limited number of alternative north/south and east/west routes contributes to peak hour congestion at the intersections and interchanges with these major thoroughfares.
