Template:CASR external links/doc

Usage
This template generates a set of external links of Caltrans traffic resources for articles on highways in California. When Caltrans revamped their web sites in 2019, they changed many of their web addresses, along with disabling deep linking to most individual highway information, which caused link rot here. Thus this template can also be used to quickly update these links should Caltrans update their web sites again.

Parameters

 * 1 or type "I" for Interstate Highways; "U" or "US" for U.S. Highways; "C", "CA" or "SR" for California state routes. If omitted, it is assumed that the highway is an unnumbered or named road.
 * 2 or route numerical portion of the route's designation.


 * For unnumbered or named roads
