About Allterra Construction

West of downtown Casper the ground breaks into bluffs and rimrock above Garden Creek, rough enough that graders earn their keep even before any snow falls on it. Allterra Construction works that broken ground — the name is literal, all-terrain the only way to describe half of what the company grades and builds on — and a storm just adds a layer to work it already knows the contours of. Wind off the high plains hits those bluffs harder than it hits the flat river bottom below, scouring some slopes bare while it loads the lee side of a ridge three feet deep within an hour. Driveways and access roads cut into that terrain hold snow unevenly for the same reason, and the crew runs equipment built for rough grading rather than a light residential blade. Allterra clears driveways, access roads, and building-site properties across Casper's broken west-side ground, plowing the same rimrock country it spends the rest of the year shaping.
