Lawmakers are hoping a state-level transportation package will put tens of thousands of Coloradans to work in construction-related industries, providing raw materials, maintenance and engineering.
The plan is at the top of the list of their agenda for the 120-day legislative session that begins Wednesday.
Democratic Senate President Peter Groff of Denver says the benefits of increased funding for transportation would ripple across the state, creating jobs for people who would support the workers on new highway and bridge projects.
A Democratic House Speaker Terrance Carroll of Denver says studies show a 10-fold increase for every dollar spent on transportation.
Legislative leaders say a lot depends on funding from Congress that won't be appropriated until after President-elect Barack Obama takes office.
Democratic leaders in Congress are expected to take up a plan to increase transportation funding to states on Monday.
