Miscellaneous notes

I-16 serves as a hurricane evacuation route for Savannah and other coastal areas. The road is designed for contraflow travel with railroad-type gates to block most entrance and exit ramps for the normally eastbound lanes. Some ramps are ungated, apparently for entrance to and exit from the contraflow lanes. Just east of exit 42 is a crossover to return all westbound traffic to the westbound travel lanes.

I-16's only two rest areas are between exits 42 and 49 near Dudley.

All of I-16 is included as part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.

History

The first part of I-16 opened October 11, 1966 to traffic between US 319 (exit 51) in Dublin to SR 29 (exit 67) near Rockledge. In 1968, the segment between US 280 to downtown Savannah was completed and opened. By the early 1970s, I-16 was completed from downtown Macon at I-75 to Jeffersonville Road near Danville. It was also extended from Dublin to Allentown. In 1973, the connection between Macon to Dublin was completed. The last part of the I-16 opened on September 22, 1978, placing it in Emanuel, Candler, and Bulloch counties and completing the connection between downtown Macon and Savannah.

Until 2000, the state of Georgia used the sequential interchange numbering system on all of its Interstate Highways. The first exit on each highway would begin with the number "1" and increase numerically with each exit. In 2000, the Georgia Department of Transportation switched to a mileage-based exit system, in which the exit number corresponded to the nearest milepost.

In 2001 the Georgia Legislature passed a resolution, to designate the Earl T. Shinhoster Interchange at the interchange with Martin Luther King, Jr. Boulevard in Savannah in honor of Earl Shinhoster, who was a Black civil rights activist. This interchange is located in the economic and cultural center for Black Savannah.

In 2003, the Georgia Legislature passed a resolution to designate I-16 in honor of James L. Gillis, Sr., a Democrat who served as a State Representative, State Senator and Director of the Georgia Department of Transportation, as the Jim Gillis Historic Savannah Parkway. Gillis' sons, Hugh and James, Jr., also served as Democratic state legislators. Hugh was a Representative from 1941 to 1953 and a State Senator from 1953 to 1955 and from 1963 to 2005. James, Jr. was a State Senator from 1945 to 1946.

Future

Due to congested traffic on rush hour in Savannah, the Georgia DOT has planned to widen the highway from two to three lanes (each way) between I-95 and I-516 (Lynes Parkway). This also includes construction on the Cloverleaf interchange at I-95. The project will start in 2019, and is slated to be complete in 2021. It is expected to cost $150 to $200 million.
