[Politics] State Constitutional Amendment for private corporate funding?

MPR Coverage of the "Itasaca Project" which will raise the gas tax, create a metro sales tax, raise license tab fees, and setup toll roads to pay for the redesign of Twin Cities poorly designed roadway infrastructure. I am all for unknotting the roadways in the Twin Cities because the frequent 3 lanes to 1 lane interchanges are annoying and time consuming. But making a Constitutional Amendment to call for taxes to pay private coporations seems very wrong (even insidious). The constitutional amendment approach is allow Gov Pawlenty to save face with his 'no increase/no new taxes' promise which is costing this state dearly in terms of the standard of living, public services, and education.
