Four level grade separation for Los Angeles parkways intersection
Proposed grade separation on State Highway 165, Arroyo Seco Harbor Parkway; basic feature is that four separate roadway levels are so arranged as to pass one another at one point in single bridge structure; two major parkways intersect one another at right angle and on different levels, while two pairs of interchange roadways occupy level each in positions bisecting quadrants made by main packway crossing. (See also Calif Highways and Pub Works v 22 n 5, 6 May-June 1944 p 8-9, 17)
