The construction of the OC Loop Bikeway Segment D will span about one mile through portions of Brea, Placentia, and Yorba Linda. The bikeway connects with the existing El Cajon Trail. The Segment D gap closure will consist of a two-lane paved recreation trail placed on top of the flood control channel and will include a series of NZ 19 sheet pile retaining walls and other improvements. In addition, the loop project has been designed in coordination with the planned replacement of the Golden Avenue Bridge. The OC Loop vision is 66 miles of seamless connections and an opportunity for people to bike, walk, and connect to many of OC's most popular destinations.more
