Contractor Hawkins Building is taking up Nebraska’s $130M I-80 enlargement, including a lane in every route plus a shoulder. Restricted closures and use of drone era purpose to ease visitors and make sure potency. Mission set for finishing touch in 2026.
Fifty years after changing into the primary state in the US to finish its interstate freeway gadget, Nebraska is rebuilding 7.6 mi. of I-80, the one interstate within the midwestern state. Paintings started at the span between Delightful Dale and the capital town of Lincoln within the spring.
The $130 million challenge will pave the prevailing freeway with new concrete and amplify the interstate from two to a few lanes in every route, plus a 12-ft. shoulder that will likely be purposeful as an extra lane in a short lived configuration.

Contractor Hawkins Building Corporate of Omaha additionally will rebuild 4 bridges — county roads — that go over I-80; assemble transient crossovers; lengthen, regulate or assemble new culverts; take away and exchange guardrail; and reconstruct the Freeway 103/NW 154th Boulevard interchange and modernize the ramp lengths to house the development. However closures of the freeway are restricted to at least one route and for handiest 8 nights all through the challenge.
“Principally, they will shut the eastbound route for one night time, and they are going to take away part of 2 of the constructions over the eastbound route,” stated Brandon Varilek, District 1 engineer of Nebraska Division of Transportation (NDOT). “Some other night time they are going to shut the westbound route and take away the opposite halves of the 2 constructions. Then, when it comes time to set the girders over visitors, they will be capable to shut them once more for one night time. The whole thing else goes to be built beneath visitors, keeping up the prevailing lanes in every route.”
The restricted closures give a contribution to probably the most largest demanding situations of the challenge — increasing the interstate whilst keeping up two lanes of freeway, Varilek stated. In Nebraska, I-80 runs from the state border of Wyoming to Omaha, bordering Iowa. The phase recently beneath development sees about 40,000 automobiles day by day. Of that 40,000, about 28 p.c are vehicles or about 11,000 vehicles day by day. Recently, any closure for upkeep backs up the interstate for miles, Varilek stated.
Probably the most distinctive sides of the challenge is that the growth is happening to the interior, slightly than out of doors. Two new lanes and a 28-ft. paved median with concrete barrier will likely be built throughout the current depressed grass median; the lanes of trip in every route will likely be separated by way of a concrete barrier, Varilek stated. No acquisition of right-of-way used to be vital.
The interior enlargement, alternatively, creates a 2nd important problem, Varilek stated. “As a result of we’re widening that inside of and filling within the grassy median, the contractor is actually restricted on house as a result of you have got two lanes of visitors in every route. We separate his paintings by way of a movable concrete barrier this is to offer protection to the contractor. However there is actually restricted house when he is operating on that inside of media.”
NDOT has been within the strategy of rebuilding the interstate for roughly 10 years, Varilek stated. The stretch from Lincoln to Omaha has been expanded to 6 lanes and NDOT is now operating to likewise amplify the I-80 to 6 lanes west to Grand Island within the heart of the state.

NDOT is hoping the long run enlargement may well be made more uncomplicated and extra environment friendly by way of studying from the paintings recently beneath means.
“We are going to going to fly the challenge a number of instances with a drone,” Varilek stated. “Drone utilization is quite new to Nebraska. We are investigating what is the very best use of this era. A couple of issues that we are taking into consideration are posting the pictures on-line to put up and spot the growth of the challenge. We are additionally having a look at doubtlessly the use of it for first responders to replace them on converting get admission to issues, as a result of get admission to will alternate during the other stages. After which additionally verifying amounts, similar to earthwork, simply to more or less take a look at out the era and spot what the constraints are and what it may be used for. We have were given much more to construct out west, so we will be able to more or less have a look at the development with this development and the phasing and spot if the paintings we’ve got finished in this phase is sensible, or if we need to make some tweaks. The ones are one of the crucial long term spaces that we expect that the drone will more or less lend a hand us out.”
The challenge is scheduled for finishing touch within the fall of 2026. CEG
