10 Day Look Ahead: Renewal Project Construction Activities

The Stanford University Medical Center Renewal Project, which will expand Lucile Packard Children's Hospital, rebuild Stanford Hospital, modernize Hoover Pavilion, and replace School of Medicine laboratories, is underway. Below is a summary of the Renewal Project's anticipated construction activities, hours of activity, and any affected lane or road closures over the next 10 days. Please click here to subscribe to our 10 day look aheads, which will be emailed every Friday and archived on the Renewal Project website.

Please note that that the scope of work and dates related are subject to change without notice. 

Welch Road Utility Project 

August 2011-September 2013 


One of the first steps in the effort to expand Packard Children's Hospital and rebuild Stanford Hospital includes utility work and surface improvements. The Welch Road Utility Project includes: replacing utility services and information technology infrastructure along Welch and Quarry Roads to serve the new hospital facilities once they are built; the widening of Welch Road; replacement of sidewalks, curbs and gutters; planting of new street trees and installation of planted medians and street lighting.


Note: Access to the Emergency Room will be maintained at all times.


This week's activities:

Thank you for your patience with our traffic pattern changes this week. During this transition, please be mindful of sharing the road with bicyclists. Cyclists who do not share the road must walk their bicycles on the sidewalks. Pedestrians must use the new designated crosswalks on Welch Road. Jaywalking is illegal and especially unsafe in active construction areas. Information Ambassadors are on site to assist you with way-finding around the medical center campus and maps are available on site or at
. Thank you!


Weekend work (10/21-10/23): 7 am- 8 pm*

Temporary power poles will go up on the outboard side of Welch Rd on Saturday, 10/22 in anticipation of the removal of the existing street lights. Continued street tree removal is also planned 10/22. New water line installation work will occur along Quarry Rd. This work will require traffic control measures. Access to the Emergency Room will be maintained at all times. 


Weekday work (10/24-10/28): 7 am-8 pm*

Concrete barriers (K Rail) have been placed on the inboard side of Quarry Rd (between Welch and continuing up to the Quarry Extension near the turn to the Emergency Department) in order to facilitate ongoing utility work. This reduces Quarry to a two lane, two direction road during this time. Access will be maintained to the Emergency Department at all times.


As of October 19th, Welch Rd is now a one-lane, one-way road going West from Quarry to Pasteur Drive. This change will be in effect for two years. We thank you for your patience regarding this significant change and ask that you please adjust your driving route accordingly. K-Rail (concrete barriers) will replace the plastic traffic delineators following this trial period. In order to increase traffic flow, street parking on North Pasteur Drive between Welch Road and Sand Hill Road (near Stanford Hospital) will be removed beginning today, October 21st. Additional staff parking is available at the Stock Farm Road lot and in PS-4. Stanford Hospital & Clinics Visitor parking will be maintained at PS-3 and at the Valet lots.


Additional planned activities include continued survey and staking work along Quarry and Welch Roads as well as tree removal on-site. Fencing will continue to be installed in the landscape along the inboard side of Welch Rd.


Preparatory utility-related work will continue on Welch Rd and Quarry Rd. This work will require some traffic control measures. Please be cautious of steel plates in the street during this time. Access to the Emergency Room will be maintained at all times.


AMC bike lockers have been posted for relocation and are expected to be relocated beginning 10/24 in preparation for closing the Blake Wilbur Parking Lot on 11/7.

*Note: In response to recent concerns over night noise from nearby residents, we requested and were granted special permission from the City of Palo Alto to alter our work hours in order to avoid overnight jackhammering activity. Our new hours of construction activity are Monday-Sunday from 7:00 am to 8:00 pm until November 23, 2011.

What to expect next weekend (10/28-10/30): 7 am-8 pm

Street tree removal planned on Welch Rd 10/29 and utility work planned along Quarry Rd and Welch Rd. This work will require traffic control measures. Please be cautious of steel plates in the street during this time. Access to the Emergency Room will be maintained at all times.

Placement of the concrete landing and ADA ramp at the east Falk temporary path will continue. The ramp is being placed over the existing walk adjacent to the relocated lockers. A second pedestrian pathway is also being installed through the Falk parking lot. This pathway will be used as the main hospital egress when the south Falk ramp is complete and open to the public. Concrete demolition for the steel ramp on the south side of the Falk Building continues.  During this time, access to the patio area and stair will be closed.
