Site access:
If you are not an LBL employee and will attend in person, you will need to be pre-approved for site access. All registered participants should have been contacted by our administrator to help you in this process.
Information about the free LBL shuttle: https://www2.lbl.gov/Workplace/Facilities/Support/Busses/all_routes.html
If you plan to ride the LBL shuttle, you must show your PRINTED site access pass and ID in order to board. The drivers will not accept the pass on your phone. Also, the LBL shuttle will not stop for you unless you wave since the stops are shared with UCB and city buses. Ride the LBL Blue Uphill shuttle route to building 65, which is the closest stop to both Building 50 (Day 1) and Building 59 (Day 2).
Parking at LBL is free but it can be difficult to find a space unless you arrive very early. We recommend riding the shuttle if possible.
