With still deep disagreements over how to pay for $6 billion in repairs and expansion to Minnesota's roads and bridges over the next decade, legislative leaders are preparing a deal that would instead provide $300 million in one-time spending and some borrowing for transportation needs.

Details are still developing as high-stakes negotiations continued Sunday between Senate Majority Leader Tom Bakk, DFL-Cook, and House Speaker Kurt Daudt, R-Crown. There remains fewer than 9 hours until the Legislature has to complete its lawmaking for the year.

A source with knowledge of the negotiations said the potential deal would appear in a single bill for both transportation and bonding.

Legislators have been working since 2015 to put together a comprehensive, 10-year transportation funding package that would provide $6 billion to maintain the state's transportation infrastructure and pay for future expansion.
