(present-day Missoula) A transportation research on U.S. Freeway 93 between Lolo and Florence is in its remaining part and is anticipated to supply quite a few suggestions to enhance security and scale back the variety of wildlife collisions inside the path.

Sarah Nicolay, mission engineer for Robert Becchia and Associates in Helena, mentioned suggestions may embody bettering lighting, decreasing speeds, bettering intersections and potential wildlife crossings.

In the end, funding will decide what the Montana Division of Transportation chooses to deal with, and when.

“A variety of residents and commuters are searching for security and operational enhancements on this space,” mentioned Nikolay. “Visitors volumes are positively growing within the Missoula and Pierrot areas.”

An environmental affect research was accomplished again in 1997 and new lanes have been added to the freeway because of this beginning in 2001. One other research was carried out in 2008 extra native enhancements and in 2020 MDT accomplished a focused research security enhancements on some websites.

Breakdowns stay an issue inside the lane, in line with a security development evaluation. From 2016 to 2020, it has recognized 198 accidents, together with two deaths. Of the accidents, 55% have been associated to animals and 42% occurred at evening.

“We all know there are a number of conflicts between wild animals and automobiles inside the path,” mentioned Nikolai. “We notice these numbers are simply incidents reported to legislation enforcement. There are different security considerations that do not essentially present up in these numbers.”

As extra land is preserved within the Bitterroot Valley, some teams are working with the Montana Division of Transportation so as to add wildlife crossings on Freeway 93 to retain the connection between the Bitterroot and Sapphire Ranges.

The continuing research additionally discovered that visitors has turn out to be extra intense attributable to its proximity to Missoula, and a few intersections make it tough to enter or entry the interstate. They discovered that the Bitterroot Path additionally causes battle with motorists.

At this level within the research, Nikolai mentioned public suggestions has known as for added visitors lights, decrease speeds, extra legislation enforcement presence, street lighting, a bodily barrier between north and south lanes, and extra lodging for wildlife.

“Our research will doc the identified use and establish methods to scale back conflicts amongst hall wildlife,” mentioned Nikolai. “Our process now could be to research these potential hall options in additional element.”

The freeway could be tough for animals to navigate, Nikolai mentioned, and several other places have been looked for potential enhancements. Components of the Lolo Creek Bridge are satisfactory for giant mammals, however the rip partitions at its base aren’t superb.

Two grizzly bears crossing the freeway this previous August have been additionally tracked and did so through a stocked lane under the street, suggesting one other attainable answer. McClain Creek was additionally recognized in a earlier research as a wildlife hyperlink between the Bitterroot and Sapphire Ranges.

Nevertheless, the sinkhole of McClain Creek is just too small for giant mammals to make use of.

The research will proceed this 12 months with outcomes anticipated within the fall. However Bob Vossen, MDT’s Missoula Area Director, mentioned development will rely upon financing.

“The problem is all funding is tied,” he mentioned. “The onerous half is we do not know but what the potential options are. We’ll attempt to see if there’s any extra fruit hanging round, one thing simple and cheap.”

Vossen mentioned the area’s funding is dedicated for the subsequent 5 years and that transferring one mission up may set one other again. Nevertheless, he mentioned security is king and quite a lot of funding sources could also be obtainable for some tasks.

One supply of funding aimed toward addressing wildlife crossings could also be obtainable in a brand new federal discretionary grant.

“We’ll look into that,” Vossen mentioned. “There may be additionally a gaggle within the state that’s serious about PPPs, and we try to work with them to establish some start-up tasks simply to get the (wildlife crossing) operation in place. With discretionary grants, we’re excited to see what these appear like as nicely.”
