Traffic on a key stretch of the eastern plains hit a hard stop late Tuesday night after a semi-truck began leaking compressed gas and forced a full closure of Interstate 70 in both directions. All lanes are shut at milepost 376 in Lincoln County, just west of County Road 36 near Limon, and authorities say they have no estimate yet for when the highway will reopen. Drivers are being urged to steer clear while emergency crews work the scene.
State patrol alerts travelers
In a late-night alert on X, the Colorado State Patrol said both eastbound and westbound lanes of I-70 at milepost 376 are closed because a semi is leaking compressed gas. The post identified the closure as west of County Road 36 and noted that there is no known time frame for reopening. Troopers are directing travelers to state road information systems for the latest word on when traffic might start moving again.
Where to get updates
The state’s official traveler information map, COTrip, is carrying updates on this closure, including lane status and any detours as they are put in place. Anyone planning east-west travel across the plains is being advised to build in extra time and choose alternate routes well before reaching the affected stretch of I-70.
Response and what to expect
Troopers say crews are actively managing the scene and that the closure could last for an extended period while the compressed gas hazard is dealt with. The Colorado State Patrol continues to point motorists to official update channels and is warning drivers to avoid the area entirely until the roadway is cleared and the interstate is safe to reopen.
