Sen. Kari Dibble and MnDOT witness Jennifer Witt used an informational hearing on Feb. 25 to preview Senate File 3988, a multi‑topic MnDOT housekeeping and efficiency bill scheduled for formal introduction on the Senate floor the following day.
The bill would raise the cost thresholds that define major highway projects in statute — described as increasing the metro threshold from about $15 million to $30 million and increasing the Greater Minnesota threshold from about $5 million to $15 million — with the stated goal of narrowing the set of projects subject to enhanced reporting. Witt noted the major projects report has grown "over 400 pages" because many smaller projects now meet the current thresholds.
Witt also outlined changes to a rail service improvement program referred to in the hearing as the Mercy program. She said the bill clarifies account structure, preserves the program's original loan authority while also permitting grants, and seeks to ensure reimbursements from railroads are redeposited and reinvested in rail infrastructure statewide.
On rail crossings, Witt told the committee the bill would prohibit the commissioner from silencing bells at public crossings, distinguishing those bells from quiet‑zone efforts to limit train horns. "This will actually prohibit any commissioner here from silencing those bells," Witt said, adding the bells serve people with visual impairments and are tied to gate operation and safety.
Witt also explained the bill would remove obsolete statutory references. She described Piney Pine Creek Airport — a cross‑border turf airport that has been closed after Canada did not renew an international agreement — and said runway maintenance costs were about $3.8 million, an explanation for why the airport should be removed from state statute to avoid confusion. She said the Hiawatha Pioneer Trail designation (created in 1964) is defunct and that other states already removed theirs.
No committee action was taken during the informational hearing; Dibble said the bill "doesn't actually exist" yet in committee and that the usual procedural steps will follow as the bill is formally introduced and considered in future meetings.
Next steps: SF 3988 will be introduced on the Senate floor and may be considered by the Transportation Committee at a later date; MnDOT offered to provide additional technical details as requested.
