Florida State Road 401

One of the shortest signed roads in the State of Florida, State Road 401 (SR 401) is a four-lane highway extending from a southern terminus at a trumpet interchange with the Martin Andersen Beachline Expressway (formerly the Bee Line Expressway) and SR A1A to a northern terminus of the south gate of Cape Canaveral Air Force Station near Cape Canaveral.

Route description

While the highway continues beyond the station gate (as Samuel E. Phillips Parkway) to the launch pads of the Kennedy Space Center, the state designation no longer does, as civilians and most military personnel not assigned to the station are generally not permitted beyond the gate.

History

Before the construction of the Kennedy Space Center and Cape Canaveral AFS, the current SR 401 was a segment of SR A1A that extended from Fort Pierce to Playalinda Beach; afterwards, but before the completion of the Bee Line, SR A1A continued northward along Atlantic Avenue into Cape Canaveral, then turning westward onto George King Boulevard and then northward onto (present-day) Samuel E. Phillips Parkway and ending at the station's gate. When the Bee Line's eastern extension was opened to traffic in 1967, SR A1A was shifted over to Astronaut Boulevard and the new toll road, and the former alignment was given the SR 401 designation (with SR 401 having its northern terminus at an intersection with SR 405 and the then-SR 402 in Cape Canaveral AFS). The section of SR 401 passing through the City of Cape Canaveral eventually lost its route signs and designation (becoming County Road 401 in the process), resulting in the current, much-shortened configuration of SR 401.

Interstate 75 in Georgia

Interstate 75 (I-75) in the U.S. state of Georgia runs north–south along the U.S. Route 41 (US 41) corridor on the western side of the state, passing through the cities of Valdosta, Macon, and Atlanta. It is also designated—but not signed—as State Route 401 (SR 401). In downtown Atlanta, I-75 joins with I-85 as the Downtown Connector.

Route description

I-75 enters Georgia near Valdosta, and it continues northward through the towns of Tifton and Cordele until it reaches the Macon area, where it intersects with I-16 eastbound towards Savannah. For northbound traffic wishing to avoid potential congestion in Macon, I-475 provides a relatively straight bypass west of that city and I-75's route.

After Macon it passes the small town of Forsyth. The freeway reaches no major junctions again until in the Atlanta metropolitan area. The first metropolitan freeway met is I-675, then followed by the Atlanta "Perimeter" bypass, I-285. It crosses inside the Perimeter and heads northeast several miles towards the Atlanta city center. I-75 then runs concurrently with I-85 due north over the Downtown Connector through the central business district of Atlanta. After the two Interstates split, I-75 makes a beeline northwest, crossing outside the I-285 Perimeter and heading towards the major suburban city of Marietta. This section of I-75 just north of I-285 has 15 through lanes, making it the widest roadway anywhere in the Interstate Highway System. North of Marietta, the final major junction in the Atlanta metropolitan area is the I-575 spur. I-75 then traverses the hilly northern Georgia terrain as it travels towards Chattanooga, Tennessee.
