Three separate crashes struck I-15 in Lehi within about 32 minutes Thursday evening, Aug. 13, blocking lanes in both directions and choking a five-mile stretch of freeway that has seen three multi-crash episodes since late July.

The first alert from UDOT Traffic on X went out around 7:06 p.m. A crash on northbound I-15 at milepost 280, near 900 North, shut down three of six lanes plus the left shoulder. UDOT estimated clearance by 8:06 p.m.

Twenty-seven minutes later, a second crash hit southbound I-15 at milepost 285 near the Point of the Mountain, blocking the center lane of five and the right shoulder. UDOT estimated that scene clear by 8:33 p.m.

Five minutes after that, a third crash struck northbound I-15 at SR-194 and 2100 North, blocking the left shoulder. Estimated clearance: 8:38 p.m.

None of the three alerts mentioned injuries, the number of vehicles involved or what caused the collisions.

A recurring pattern

Thursday's pileup marks the third time in 16 days that multiple crashes have stacked up on the Lehi I-15 corridor. Two crashes hit northbound lanes within 25 minutes on the evening of July 29, as we reported July 30. Three more struck the I-15 and Legacy Parkway corridor on the morning of Aug. 10, generating delays of 30 minutes or more for drivers heading to and from Lehi, Alpine, Highland and Cedar Hills.

Construction zone overlap

The SR-194 crash site sits inside UDOT's active $621 million 2100 North freeway connector construction zone. That project broke ground in March and is expected to run through late 2028, linking I-15 directly to Mountain View Corridor. Construction-related lane shifts and shoulder work along the stretch will continue for more than two years, according to UDOT estimates.

The Lehi Police Department had not released incident reports for Thursday's crashes as of Friday, Aug. 14. After the July 29 crashes, Lehi PD also did not release reports the following day.
