Looking at Tomorrow’s Traffic Today: In Pasco County, the southbound I-75 exit ramp to State Road 52 will be closed Tuesday night from 9:00 p.m. to 9:30 p.m. Drivers must continue south on I-75 until they reach the next exit at State Road 54. At this point drivers can exit the interstate and then re-enter at SR 54 to travel north and exit at SR 52. Allow an extra 20 minutes for this detour.
