Construction and Parking
Construction progress of the Frank J. Malina Laboratory as of August 2026.
Parking and Traffic
- Portions of Holliston Avenue will be closed to vehicle traffic to accommodate upgrades to Caltech's electrical infrastructure. The road closures will impact the access routes to the Holliston Parking Structure. The parking structure will remain open throughout the construction period. The work will occur from 7 a.m. to 4:30 p.m. on weekdays and in phases as follows:
- Phase 1 (detour map): From Monday, August 17 through Friday, August 28, vehicles will not be able to access the Holliston Structure from Del Mar. During this time, the Holliston Structure will be accessible from the south via San Pasqual.
- Phase 2 (detour map): From Monday, August 31 through Friday, September 4, vehicles will not be able to access the Holliston Structure from San Pasqual. During this time, the Holliston Structure will be accessible from the north via Del Mar.
- If you have questions about this period of road closure, call (626) 395-4717 or email [email protected].
- From June until mid-September, Metro's Bus Rapid Transit construction at Hill Avenue and Green Street will cause southbound and northbound lane reductions on Hill Avenue (Colorado Boulevard–Cordova Street) and eastbound reductions on Green Street. Construction runs Monday–Friday, 7am–4pm, though lane closures remain in place 24/7. Please plan extra travel time or use alternate routes during this ~3-month station build. Read the full construction notice for details.
- Visitor parking at Caltech is moving to HonkMobile (HONK) over the coming weeks. New payment signs will be installed in campus lots and structures, replacing existing pay stations. For more information, visit Caltech's Mobile Payments for Visitor Parking webpage.
