Interstate 3

Interstate 3 (I-3), the Third Infantry Division Highway, is a proposed Interstate Highway in the United States to run from Savannah, Georgia, north to Augusta, Georgia, and Knoxville, Tennessee. The roadway was proposed in the same federal highway measure that gave birth to a proposal for I-14.

History

In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) was signed into law by then-President George W. Bush. The act included the proposed corridors for the planned I-14 (specifically as the 14th Amendment Highway), and I-3 (as the 3rd Infantry Division Highway). The legislation did not provide the official numbering, nor did it provide funding for the highways.

The proposed numbering of the highway does not follow the pattern of the existing Interstate Highway grid but is noted to salute and honor the Third Infantry Division of the United States Army, based at Fort Stewart, near Savannah, Georgia.

According to the Georgia Department of Transportation, the existing Savannah River Parkway, which carries the designations SR 555 and SR 565, is open to traffic. It begins just northwest of Savannah at the intersection of I-95 and SR 21/SR 30. It travels northwesterly along SR 21, paralleling the Savannah River, to Millen, where it meets US 25. From Millen, the roadway follows US 25 to I-520 in Augusta. A western branch of the Savannah River Parkway travels from I-16 south of Statesboro north and northwestward (following US 25) to meet the main parkway roadway in Millen.

Interstate H-3

Interstate H-3 (abbreviated H-3) is an intrastate Interstate Highway located on the island of O'ahu in the state of Hawaii in the United States. H-3 is also known as the John A. Burns Freeway. It crosses the Ko'olau Range along a viaduct and through the 5,165-foot-long (1,574 m) Tetsuo Harano Tunnels as well as the much smaller Hospital Rock Tunnels.

Despite the number, signage is that of an east–west highway. Its western terminus is at an intersection of Interstate H-1 at Hālawa near Pearl Harbor. Its eastern end is at the main gate of Marine Corps Base Hawaii (MCBH). This route satisfies the national defense purpose of connecting the Marine Corps base with the U.S. Navy port at Pearl Harbor off Interstate H-1.

Orders for the freeway were granted in 1960, followed by planning stages. Construction, amid enormous community protest, was begun in the late 1980s, although the road did not open until December 12, 1997. Environmental complaints and legal challenges halted construction at many points. Construction resumed during the late 1980s due to an unprecedented move by U.S. Senator Daniel Inouye, who in 1986 had the freeway exempted from most environmental laws as a rider on a Department of Defense budget bill.
