The Willow Road/U.S. 101 interchange between Newbridge Street and Bay Road will be closed for 54 hours, from 10 p.m. on Friday, Oct. 5, through 4 a.m. Monday, Oct. 8. The ramps will reopen at 6 a.m. Monday.

Detours will be in place during this time, and people will be directed to access the freeway from Marsh Road or University Avenue using Bayfront Expressway and Middlefield Road, according to Menlo Park city staff.

The freeway will remain open, as will other local roads.

When the bridge reopens Monday, the traffic patterns and interchange layout will be different. To turn from Willow Road onto both north- and south-bound U.S. 101, people will have to turn right. Off-ramps will be moved to the opposite side of Willow Road from where they area now, and traffic lanes will be moved to the outside of the construction area on Willow Road.

The closure will mark the project's progress into the third of four stages of the two-year effort to rebuild and upgrade the interchange.
