The Historic Columbia River Highway is an approximately 75-mile-long (121 km) scenic highway in the U.S. state of Oregon between Troutdale and The Dalles, built through the Columbia River Gorge between 1913 and 1922. As the first planned scenic roadway in the United States, it has been recognized in numerous ways, including a listing on the National Register of Historic Places as a National Historic Landmark, designation as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and considered a "destination unto itself" as an All-American Road by the U.S. Secretary of Transportation. The historic roadway was bypassed by the present Columbia River Highway No. 2 from the 1930s to the 1950s, leaving behind the old two-lane road. The road is now mostly owned and maintained by the state through the Oregon Department of Transportation as the Historic Columbia River Highway No. 100 or the Oregon Parks and Recreation Department as the Historic Columbia River Highway State Trail.

U.S. Route 199 (US 199) is a U.S. Highway in the states of California and Oregon. The highway was established in 1926 as a spur of US 99, which has since been replaced by Interstate 5 (I-5).

In Oregon, US 199 is officially known as Redwood Highway No. 25. The majority of the road in California is the Smith River Scenic Byway, a National Forest Scenic Byway. The first roadway, a plank road, from Crescent City was established in May 1858, and before the US 199 designation was applied to the highway, the roadway was designated Highway 25 and Route 1.

Owned by the Virginia Department of Transportation (VDOT), it is operated and maintained by Elizabeth River Crossings under a 58-year public–private partnership concession agreement. Formerly a toll-free facility, open road tolling was implemented on February 1, 2014 by VDOT to help finance repairs and expansion to the tunnel.

Engineering Economics in Civil Engineering, also known generally as engineering economics, or alternatively engineering economy, is a subset of economics, more specifically, microeconomics. It is defined as a "guide for the economic selection among technically feasible alternatives for the purpose of a rational allocation of scarce resources." Its goal is to guide entities, private or public, that are confronted with the fundamental problem of economics.
Public-private partnerships are cooperative arrangements between two or more public and private sectors, typically of a long-term nature. In the United States, they mostly took the form of toll roads concessions, community post offices and urban renewal projects. In recent years, there has been interest in expanding P3s to multiple infrastructure projects, such as schools, universities, government buildings, waste and water. Reasons for expanding public-private partnership in the United States were initially cost-cutting and concerns about Public debt. In the early 2000s, P3s were implemented sporadically by different States and municipalities with little federal guidance. During Obama's second term, multiple policies were adopted to facilitate P3 projects, and Congress passed bills in that direction with overwhelming bipartisan support. My Brother's Keeper Challenge is an example of a public–private partnership. Some Private-public partnerships were carried out without incident, while others have attracted much controversy.
