Document Type
MND - Mitigated Negative Declaration
Present Land Use
PLU: Roadway and bicycle/pedestrian trail; Z: Parks and Rec at both sites; GP: Roadway and parks for both sites
Document Description
The proposed project involves the construction of two overcrossings or bridges along the existing Iron Horse Trail alignment. The preliminary conceptual design for the Crow Canyon overcrossing would likely consist of a tied arch main spa, girder, or a design of similar appearance that would cross over Crow Canyon Rd. The Bollinger Canyon overcrossing would likely consist of a cable-stayed main span with a single tower located on the south side of Bollinger Canyon Rd or a design of similar appearance. Two options are considered for the preliminary conceptual tower design including a single mast or an A-frame. For both spans, from the northern to southern landings, the total length of the new overcrossing would be between approx 1,200 and 1,400 lf. The width of both spans would range between approx 16 and 20 feet.
