Options for traveling to Wausau, Green Bay and Dubuque, Iowa ? and points along the way ? expand dramatically Thursday with the start of three direct bus routes to those cities out of Madison. The routes are operated by Lamers Bus Lines of Green Bay and are subsidized by state and federal money. Tickets for the buses, which will arrive and depart from the UW-Madison campus, will be $45 one way. All of the buses running the new routes would arrive and depart from Langdon Street in front of the Memorial Union.
