Driving in the Valley this weekend could be fairly painless, save for one extended closure.
• Eastbound Union Hills Dr. on-ramp to southbound State Route 51 will be closed from 6 a.m to 4 p.m. Saturday for electrical system work.
• Litchfield Rd. will be closed for about two months between Wigwam Blvd. and Village Pkwy. from Jan. 7 to March 8 for pedestrian underpass construction.
