Loop 375 is open again after two separate crashes forced a stretch of the highway to close early Friday morning.
The wrecks happened on the northbound lanes near the intersection with Montana. The first happened around midnight, the second about an hour later.
The more serious of the two involved a motorcycle. The rider was transported to a hospital in critical condition.
The other crash was a rollover, but no serious injuries were reported.
The highway has since reopened. No word if weather was a factor in any of the wrecks.
