Crain's Chicago Business obtained a copy of a speech Chicago Mayor Rahm Emanuel will deliver today on his vision for new infrastructure for the city: the mayor lays out $7.2 billion in infrastructure projects over the course of four years. This includes a new runway for O'Hare International Airport, which Emanuel wants airlines to pay for, even as two new runways currently being constructed and are slated for completion in 2015.

Emanuel also foresees 100 CTA stations being rebuilt and renovated, and literally half of all the city's 2,000 miles of streets repaved.

How will this be paid for? Emanuel once again mentions the "Infrastructure Trust" of public-private partnerships, as well as city money, and money from city agencies -- like the cash-strapped Chicago Public Schools.
