The Let’s Go Austin Political Action Committee, formed to campaign for Austin’s November rail and roads bond proposition, will formally kick off its campaign Wednesday with a noon rally on the plaza at Austin City Hall. Let’s Go Austin campaign manager Lynda Rife said the event is the beginning of a three-month effort to educate voters about Proposition 1. The November bond proposal totals $1 billion, with $600 million dedicated to the first phase of the urban rail system and $400 million dedicated to major road projects, a new Austin Traffic Command Center, and engineering studies for future road fixes and expansion of the urban rail system. Council members, business leaders and others are scheduled to speak at the PAC event Wednesday. Early voting for the Nov. 4 election begins Oct. 20.
