Colorado's clogged highways and roads got no love from voters Tuesday night, and dueling propositions may be to blame.

Propositions 109 and 110 would have provided millions of dollars for highway improvements but sought to go about it in different ways. Voters rejected both ballot issues with more than 60 percent voting against the proposals, according to results late Tuesday night.

Proposition 109, also known as Fix Our Damn Roads, authorized $3.5 billion in bonding authority to be paid back over 20 years from the state's general fund. Proposed by Jon Caldara and his Independence Institute, 109 laid out 66 specific funding projects, including widening I-25 from Colorado Highway 7 near Erie to Colorado Highway 14 in Fort Collins. It had only 39 percent support from voters.

Its countermeasure, Proposition 110, would have raised the state's sales tax 0.62 percentage points, or about 6 cents on a $10 purchase, to generate up to $6 billion for transportation projects around the state, including I-25. It would have also divided part of the money between state highways, cities, counties and a dedicated multimodal fund. It had only 40 percent support from voters.

The state's sales tax rate is 2.9 percent. Prop 110 would have brought it to 3.52 percent, in addition to local and county taxes. Fort Collins' sales tax, including state taxes, is currently 7.3 percent; with Proposition 110, it would have been 7.92 percent.

This isn't the last voters have seen of road-improvement efforts. Now that both propositions failed, the state reverts to Senate Bill 1, passed in this year's legislative session. It authorizes a 2019 ballot measure that would ask voters for bonding authority of about $3 billion to be repaid by the general fund over 20 years.
