Alaska DOT says mechanic shortages and brine trade-offs shape winter road strategy

Alaska Department of Transportation and Public Facilities officials told the Senate Transportation Committee on March 6 in Juneau that mechanic vacancies and equipment age have become central constraints to winter road maintenance, and that the department is balancing safety benefits of brine anti-icing against corrosion concerns raised by residents.

For the record, Andy Mills, legislative liaison and special assistant for the Department of Transportation and Public Facilities, opened the presentation and turned fleet questions over to the state equipment fleet manager, Brad Bialzma, who said, "My name is Brad Bialzma. I'm the state equipment fleet manager." The committee was chaired by Senator Bjorkman; Senators Keel, Tobin and others asked questions during the presentation.

The discussion matters because snow and ice removal is the primary winter function for DOT&PF and affects road access, transit and economic activity across urban and rural Alaska. Committee members pressed DOT on staffing, contracting and how brine and other anti-icing choices affect vehicle corrosion and visibility on winter roads.

DOT officials told senators the state equipment fleet maintains roughly 1,000 pieces of heavy equipment used for highways and for rural airports. Brad Bialzma said that vacancy rates for heavy-equipment mechanic positions have grown and are a driver of increased contracting. Committee members and DOT staff said the state has tried multiple recruitment pathways including Avtec and vocational schools and has funded CDL training to lower hiring barriers.

Officials said starting wages vary by location: "there's a geographic differential" and Anchorage starting pay is about $28 to $29 an hour while remote postings pay 30%–40% more, according to DOT staff. DOT described the wage situation as generally lower than private-sector employers in many areas, and said that as the available pool of qualified mechanics shrinks, pay will likely need to rise to attract workers.

The department said it manages most routine maintenance in-house and uses private shops chiefly for work that requires shop space or specialized tooling (example: bodywork or windshield replacement). Bialzma said contracting out has risen in recent years as a necessary response to a roughly 33% vacancy rate in mechanic positions; he added the department monitors cost and timeliness when choosing to contract.

Committee members pressed DOT on redundancy during high-impact storms and on whether dependence on private contractors undermines DOT’s core responsibilities. DOT representatives said the priority is keeping the fleet operable in-house, but that carefully selected private partnerships and supplemental contracts are used to fill gaps and to accelerate work on priority-3 and -4 routes and sidewalks during large events.

Brine anti-icing use drew extended discussion. Andy Mills described brine as a liquid preparation (a roughly 23.3% sodium chloride mix in DOT examples) applied directly to pavement or sand to improve persistence and reduce the scatter-and-bounce loss associated with solid salt. Mills said corrosion inhibitors ("often 5 to 10%", per his remarks) are added to lower the corrosion profile. He said brine was pursued as a cost-saving and operational measure beginning around 2014 and that anti-icing can reduce the number of passes needed when snow falls shortly after treatment.

Senators and some residents raised corrosion concerns. Senator Bjorkman and others recounted constituent complaints on the Kenai Peninsula that brine is accelerating rust on vehicles and equipment and urged DOT to reduce use. DOT officials described a set of local responses on the Kenai Peninsula: a 60% reduction in brine use in the most recent winter, a no-brine pilot on Funny River Road that residents reported favored, and additional operator training and community engagement. Mills said the department uses a decision flowchart that considers pavement temperature, forecast and surface condition and does not apply brine in every circumstance.

DOT also described changes to winter maintenance priorities and sidewalk clearing. Staff said the department has decoupled sidewalk prioritization from road prioritization in Anchorage, created GIS maps for pedestrian assets and is expanding supplemental contracts to help clear lower-priority roads and sidewalks sooner after storms. Committee members noted the published service windows on the Anchorage map: up to 12 hours for a Priority 1 road after a storm but up to 48 hours for a Priority 1 sidewalk, a disparity that drew further questions about equity and pedestrian access. DOT said those time frames are broad and event-dependent.

On legal and policy context, DOT staff said the department was responding to legislative intent language directing a review of winter road maintenance priorities and functional classification (a 10-year census-linked review that helps set priority status). DOT scheduled public engagement tied to that review and cited dates for outreach in late March and April.

The presentation closed with DOT noting improvements in equipment procurement lead times: historically 18 months to two years, with recent deliveries accelerating — DOT reported numbers of plow trucks received rising from six in FY22 to 20 in FY24 and a projected 30 in FY25. Chair Bjorkman and other senators said further oversight and follow-up (including a subcommittee discussion on Seward Highway maintenance) were expected.

"That concludes the presentation," Andy Mills said at the end of the session.

DOT provided technical details and said it would continue public outreach; senators signaled interest in following procurement, vacancy, contracting costs and local corrosion data as the department continues pilots and adjusts brine use.
