LEHI — May will mean a few more headaches for Utah County drivers.

The Utah Department of Transportation construction crews on the Utah County I-15 Corridor Expansion are scheduled to close University Parkway in Orem from 400 West to the I-15 interchange nightly beginning May 2 through May 17.

The shutdowns are the first in a series of closures during the month to convert the intersection at University Parkway and Sandhill Road into a continuous flow intersection — the first intersection of its kind in Utah County.

Construction will occur in three phases of closures scheduled to take place between May 2 and May 21, UDOT announced.

In phase one, University Parkway from 400 West to the I-15 interchange is scheduled to close nightly from approximately 9 p.m. to 5:30 a.m. for pavement removal and replacement. The interchange is also scheduled to close periodically for paving.

During the second phase, left turns from University Parkway to Sandhill Road will be prohibited and traffic lanes will be shifted as work progresses. The north half of the Sandhill Road intersection and the direct access ramp from College Drive will also be closed during this phase for paving.

In phase three, University Parkway is scheduled to close from 400 West to the I-15 interchange as early as May 17 at 9 p.m. through May 21 at 5:30 a.m. to complete paving, lane marking and signal work as well as opening the University Parkway-Sandhill Road intersection as a CFI.

During the closures, I-15 will remain open and drivers should use Geneva Road or 400 West to access east-west routes, Utah Valley University and area businesses. Drivers can use Orem Center Street, 800 North or Provo Center Street for I-15 access.

The intersection at University Parkway and Sandhill Road is used by nearly 70,000 cars per day. Converting it to a CFI will improve the flow of traffic through the intersection by 20 percent and will enhance safety for drivers turning left from University Parkway onto Sandhill Road.

“These closures will allow us to complete this new innovative intersection and reduce congestion in the area six months ahead of schedule,” said UDOT spokeswoman Mindy Nelson. A video with more information about the new intersection and how to navigate it is available at

“We recognize two weeks of night closures at University Parkway will create inconveniences for drivers, which is why we recommend planning ahead and using alternate routes,” Nelson said.
