Lynes Parkway) is a {{convert|6.49|mi|km|adj=mid|-long}} auxiliary Interstate Highway mostly in the coastal city of Savannah, located in the east-central portion of the U.S. state of Georgia. It is a spur route of I-16. For its entire length, I-516 is concurrent with State Route 21 (SR 21), upon which I-516 was designated over in 1985. It was formerly also signed as SR 26 Loop.[4][5] The highway also carries unsigned State Route 421 (SR 421) to ensure that all Interstates in Georgia had 400-series reference numbers.[6][7] Route descriptionI-516 begins in the northeastern part of Garden City, as a freeway continuation of SR 21 (Augusta Road), with which I-516 travels concurrently for its entire length. The two highways travel to the southeast to an interchange with SR 25/SR 26 Connector (Burnsed Blvd), which leads to US 80/SR 26. However, only US 80 is signed at this exit. At this interchange, SR 25 joins the concurrency. In the midst of this interchange is a crossing over the Dundee Canal. The three highways pass just southwest of the Mary Calder Golf Club. After beginning a curve to the south-southwest is an interchange with SR 25 Connector (West Bay Street). Here, US 80 and SR 26 join the concurrency. The five highways cross over the Savannah–Ogeechee Canal. A short distance later is an incomplete interchange with West Gwinnett Street. Almost immediately is an interchange with I-16/US 17 (Jim Gillis Historic Savannah Parkway). At this point, US 17 joins the concurrency. A short distance later is an incomplete interchange with Tremont Road. At Ogeechee Road, US 17/SR 25 depart the concurrency to the southwest, while US 80/SR 26 depart to the northeast. I-516/SR 21 continue to the south-southwest and have an interchange with the northern terminus of Veterans Parkway, just before curving to the east-southeast. They cross underneath, but do not have an interchange with, Liberty Parkway. They cross over some CSX Transportation railroad lines just before crossing over the Springfield Canal. Just west-northwest of Mildred Street, the freeway ends and the two highways continue to an intersection with Montgomery Street. At this point, I-516 meets its eastern terminus, while SR 21 (DeRenne Avenue) continues to the east-southeast.[2] I-516 is one of a small handful of interstate highways that is not a freeway for its entire length. The southeastern-most half mile downgrades to an expressway with a 45 mile-per-hour speed limit, an at-grade intersection at Mildred Street, a right turn lane onto the De Renne Avenue frontage road, and a 35 mile-per-hour school zone designation following the frontage road right turn to the interstate's eastern terminus at Montgomery Street. The southbound entrance onto Mildred Street is often closed by concrete barriers, as it's primarily used to directly access Hunter Army Air Field from the interstate. The entire length of I-516 is included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.[3] History1920s to 1960sThe road that would eventually be designated as I-516 was established at least as early as 1919 as a segment of SR 21 from the current western terminus of I-516 to an intersection with SR 26.[4] In 1926, US 17/SR 25 were designated along this section of SR 21.[5][6] Between 1963 and 1966, I-16 was under construction in Savannah, and the majority of what would become I-516, from Augusta Avenue to its current eastern terminus, was being proposed as SR 26 Loop.[7][8] Later in 1966, SR 26 Loop was completed (but not to freeway standards) from just east-southeast of what is now the Veterans Parkway exit to La Roche Avenue, with a proposal to extend it northward through Savannah State University. The rest of the proposed route was also under construction at that time. Also, the construction of I-16 continued to proceed.[8][9] In 1967, the section from I-16 to just east-southeast of what is now the Veterans Parkway exit was still under construction but scheduled to open "Spring '68". I-16 was completed in Savannah at this time.[9][10] In 1968, the segment of SR 26 Loop from I-16 to just east-southeast of what is now the Veterans Parkway exit was opened (at freeway standards).[10][11] 1970s to 2000sBy 1970, the segment from Augusta Avenue to I-16 was opened (at freeway standards).[11][12] Later that year, there was a proposal to extend the western terminus a little farther to the west, to meet what is now US 80/SR 25 Connector/SR 26.[12][13] Between 1977 and 1979, the entirety of SR 26 Loop, with the exception of the segment between Skidaway Road and La Roche Avenue, was redesignated as an extension of SR 21. The Skidaway–La Roche section was removed from the state highway system. Due to this, the proposal to extend SR 26 Loop from La Roche was removed, as well.[14][15] By March 1980, the freeway portion was extended to the west, roughly along the same alignment proposed in 1970.[15][16] In 1982, the freeway portion was extended a little more to the west, nearly to the current western terminus of I-516.[17][18] In 1985, the entire highway from its then-current western terminus at Burnsed Blvd to Montgomery Street was designated as I-516. The freeway portion was extended westward to the interchange with SR 25 (Burnsed Blvd) and eastward to the current eastern terminus. Also US 17/SR 25 and US 80/SR 26 were re-routed along the freeway, from the West Bay Street exit to the Ogeechee Road exit.[19][20] In 1995, US 17 had a major re-routing through the city of Savannah to its current alignment. Therefore, it is concurrent with I-516/SR 21 from the I-16 exit to the Ogeechee Road exit.[21][22] In 2001, SR 421 was designated along I-516's length.[23][24] Exit list{{jcttop|exit|state=GA|county=Chatham|length_ref=[2]}}{{GAint|exit|location=Garden City |lspan=2 |mile=0.0 |type=concur |exit=9 |road={{jct|state=GA|SR|21|dir1=north|name1=Augusta Road|city1=Springfield}} |notes=Western terminus; western end of SR 21 concurrency }}{{GAint|exit |mile=0.1 |type=concur |exit=8 |road={{jct|state=GA|US|80|name1=SR 25 north / SR 26 Conn. south (Burnsed Road)|to2=y|SR|26}} |notes=Exit signed only as "U.S. 80"; western end of SR 25 concurrency; northern terminus of SR 26 Conn. }}{{GAint|exit |location=Savannah |lspan=6 |mile=1.3 |exit=7B |road={{jct|state=GA|SR-Conn|25|dab1=Savannah|name1=West Bay Street|city1=Downtown Savannah}} }}{{GAint|exit |type=incomplete |mile=1.6 |exit=7A |road={{jct|state=GA|US|80|SR|26|dir1=west|dir2=west|name2=Augusta Avenue|city2=Statesboro}} |notes=Westbound exit and eastbound entrance only; western end of US 80/SR 26 concurrency }}{{GAint|exit |type=incomplete |mile=2.3 |exit=6 |road=Gwinnett Street – Amtrak station |notes=Westbound exit and eastbound entrance only }}{{GAint|exit |type=concur |mile=2.5 |exit=5 |road={{jct|state=GA|I|16|US|17|dir2=north|name1=Jim Gillis Historic Savannah Parkway / SR 404|city1=Savannah|city2=Macon}} |notes=I-16 exits 164A-B; western end of US 17 concurrency }}{{GAint|exit |type=incomplete |mile=3.2 |exit=4 |road=Tremont Road |notes=Westbound exit and eastbound entrance only }}{{GAint|exit |type=concur |mile=3.8 |exit=3 |road={{jct|state=GA|US|17|dir1=south|US|80|dir2=east|SR|25|dir3=south|SR|26|dir4=east|name4=Ogeechee Road|city1=Brunswick|city2=Downtown Savannah}} |notes=Eastern end of US 17, SR 25, and US 80/SR 26 concurrencies }}{{GAint|exit |location=none |mile=4.7 |exit=2B |road=Veterans Parkway south – Georgetown |notes=Northern terminus of Veterans Parkway }}{{GAint|exit |location=Savannah |mile=6.9 |type=concur |exit=2A |road={{jct|state=GA|SR|21|dir1=south|name1=Derenne Avenue}} |notes=Eastern terminus; roadway continues as SR 21; eastern end of SR 21 concurrency }}{{Jctbtm|col=7|keys=concur,incomplete}} See also
