In mid-August (20th), lanes on both northbound and southbound I-15 in Orem will be split to accommodate bridge and road construction. The split will be similar to the configuration currently in effect in the American Fork area. Trucks will be allowed to use all lanes in this area. Drivers will need to stay in the right two lanes in order to use the Orem exits. Motorists should use extreme caution when approaching this traffic configuration and obey signs and barriers.
