You are abusing link_to. The syntax for linking to a pregenerated  
location is:

<%= link_to 'Trave', @link, #the other arguments %>

Otherwise, you generate a route within you controller with @link  
as :action parameter.
And parameters will (and have to) be escaped by link generation.

This is really much more of a question for the rails mailing list.
