Interstate 49 (I-49) is a north–south Interstate Highway that exists in multiple segments: the original portion entirely within the state of Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, three newer sections in Arkansas, and a new section that opened in Missouri. Its southern terminus is in Lafayette, Louisiana, at I-10 while its northern terminus is in Kansas City, Missouri, at I-435 and I-470. Portions of the remaining roadway in Louisiana, Arkansas, and Texas, which will link Kansas City with New Orleans, are in various stages of planning or construction.
The Delaware Memorial Bridge is a dual-span suspension bridge crossing the Delaware River.

It is also one of only two crossings of the Delaware River with both U.S. Highway and Interstate Highway designations, the other being the Benjamin Franklin Bridge.

The Bear Mountain Bridge, ceremonially named the Purple Heart Veterans Memorial Bridge, is a toll suspension bridge in New York State. It carries US 6 and US 202 across the Hudson River between Bear Mountain State Park in Orange County and Cortlandt in Westchester County.

Forgottonia, also spelled Forgotonia, is the name given to a 16-county region in Western Illinois in the late 1960s and early 1970s. This geographic region forms the distinctive western bulge of Illinois that is roughly equivalent to "The Tract", the Illinois portion of the Military Tract of 1812, along and west of the Fourth Principal Meridian. Since this wedge-shaped region lies between the Illinois and Mississippi rivers, it has historically been isolated from the eastern portion of Central Illinois.
