I-80 WB tunnel in Wyoming reopening Wednesday after months-long closure

The Wyoming Department of Transportation and contract crews will reopen the westbound tunnel on Interstate 80 near Green River to traffic on the morning of Wednesday, Oct. 29, for the first time since it was closed in February following a Feb. 14 fatal crash.

With the recent delivery of electrical components, and some use of temporary materials, crews were able to expedite work on the lighting system and signage, allowing the WB tunnel to reopen sooner than expected. The EB tunnel has been open to traffic at a reduced speed and with vehicle size restrictions since late February.

WyDOT officials and contractors have been working quickly to get traffic moving in both tunnels before the winter season. The WB tunnel will reopen at a reduced speed of 35 mph and without the completion of all the lighting infrastructure.

“Since we will only have one side of the tunnel lights operational in the westbound tunnel, we will have to reduce the speed limit to increase the level of safety for drivers,” said WyDOT District 3 construction engineer Peter Stinchcomb.

Though the WB tunnel will be open to traffic, WyDOT is encouraging drivers to put down distractions, follow the reduced speed limit and drive cautiously through the area. Following opening of the WB tunnel, crews will need to remove the concrete barrier, reset the cable barrier and remove all the traffic control devices in the EB tunnel. To do so, I-80 EB traffic will be detoured through Green River on Flaming Gorge Way, beginning at 9 a.m. on Wednesday, Oct. 29 until dark, and again on Thursday, Oct. 30 from 7 a.m. to 7 p.m. Contractors hope to finish the work by Thursday evening.

If delays occur and contractors are unable to finish by Thursday evening, crews will return Monday, Nov. 3. Traffic will not be diverted through Green River on Oct. 31 due to increased foot traffic for Halloween.

“It was imperative that we not run interstate traffic on Flaming Gorge Way on Friday because of Halloween,” said WyDOT resident engineer Clint Lockman. “We know there will be additional foot traffic in the area for Halloween activities, so we will be working to finish the removal of the traffic control in the eastbound tunnel by Thursday evening.”

The legal-load-only restriction -- which is 8.5 feet in width -- will remain in place until both EB and WB tunnels are open to two lanes of traffic. Transportation officials will be monitoring the traffic flow and will make adjustments accordingly. Oversize vehicles should still contact the Wyoming Highway Patrol’s oversize loads permit office to check for restrictions.

Construction will resume on the WB tunnel in the spring, when crews will return to complete the lighting for both lanes. Completion of the project will be dependent on material delivery, but the initial date is set for June 30, 2026. Drivers can expect similar conditions, with head-to-head traffic in the EB tunnel this spring while crews complete the final stages of work.

Diesel prices give back much of recent month’s decreases

After having fallen more than 13 cents since the beginning of October, diesel prices saw a significant uptick in the most recent week to give back most of the improvements seen this month.

According to the Energy Information Administration, diesel prices jumped 9.8 cents during the week ending Oct. 27.

With that increase, the national average for a gallon of on-highway diesel now stands at $3.72 a gallon, up from $3.62 last week.

All regions except New England saw increases during the most recent week, yet the Midwest and Rocky Mountain regions saw the largest upticks of 15.1 cents and 10.1 cents, respectively. New England’s average price declined by a penny.

California continues to hold the nation’s most expensive diesel at $4.93 a gallon, while the cheapest diesel is in the Gulf Coast region at $3.35 a gallon.

Prices in other regions, according to EIA:

  • New England -- $3.93
  • Central Atlantic -- $3.88
  • Lower Atlantic -- $3.64
  • Midwest -- $3.72
  • Rocky Mountain -- $3.69
  • West Coast less California -- $4.10

ProMiles’ diesel averages during the same week fell by 0.8 cents to $3.59/gallon nationwide. According to the ProMiles Fuel Surcharge Index, the most expensive diesel can be found in California at $5.05, the cheapest in the Gulf Coast region at $3.22.

WEX fuel discounts for owner-ops now available through Trucker Path

The fuel discounts offered on the 10-4 by WEX app for owner-operators and small fleets are now available on the Trucker Path app, the companies announced.

This integration provides Trucker Path app users with access to fuel discounts provided by the 10-4 by WEX app, which include includes the 7FLEET Diesel Network (Speedway, Stripes, and 7-Eleven), Circle K, Love's Travel Stops, Maverik, Sapp Bros., TA, Petro Stopping Centers and TA Express, RaceTrac, and Road Ranger.

"This strategic alliance with the 10-4 by WEX app offers our community of drivers lower fuel prices and a quick, easy and secure way to pay -- it's that simple," said Chris Oliver, CMO of Trucker Path. "Time is money and fuel is a tremendous expense. Our users will save on both. They'll continue to rely on Trucker Path for the fastest and safest routes while also lowering their fuel costs along those routes."

Trucker Path users will be able to easily find the best fuel discounts from the 10-4 by WEX app and immediately navigate to that location, the company said. Additionally, operators can also find details on parking availability, the services and amenities offered, and the ratings and reviews from other commercial drivers.

The 10-4 by WEX app is a free app, offering nationwide diesel discounts at thousands of U.S.-based truck stops. Designed to provide owner-operators and small fleets with instant savings on diesel, there are no credit checks, no transaction fees and no need for a physical card at the pump.

"Building and maintaining healthy profit margins is a complex challenge for truckers, and this collaboration with Trucker Path is an excellent way to help them save on costs," said Tim Hampton, senior vice president and general manager of Over-the-Road at WEX. "Fuel makes up nearly one-third of expenditures for independent owner-operators, with approximately $50,000 spent on fuel every year on average. Our shared goal with Trucker Path is to streamline savings on every gallon purchased while making the process easy for hard-working truckers to make every cent matter."
