An emergency project to improve conditions on the US Highway 101 undercrossing at Castillo Street continues with concrete work on sidewalks and the pavement.

This project will include a reinforced concrete slab placed three to four inches above the pavement and above a geo-thermal membrane to direct the water beneath the surface to nearby drainage channels.  This concrete is expected to be poured in mid-July.

Castillo Street remains closed from US Highway 101 to the Union Pacific Railroad tracks for the next two months.  The southbound on/off ramps to US Highway 101 at Castillo Street  remain closed for the duration of this project.  Motorists headed southbound on US Highway 101 may use the off-ramps at West Carrillo Street or Garden Street.  Local traffic near Castillo Street will detour onto State Street or Garden Street.

  • The Santa Barbara Metropolitan Transit District (MTD) has established an Americans with Disabilities Act (ADA) bus stop for Lines 5 and 15x on eastbound Montecito Street at Bath Street for the duration of this project.

Caltrans has installed signs to direct motorists to the Santa Barbara Harbor area  which is fully open during this project.  Detour signs have been posted near Castillo Street to assist motorists, bicyclists and pedestrians during this project.                  

The contractor for this $1.5 million project is Security Paving of Sylmar, CA.  This project is expected to be completed by the end of August.  

Caltrans reminds motorists to move over and slow down when driving through highway construction zones.

Castillo Street Undercrossing Project Continues

After the Fiesta parade the horses and carriages return to Pershing Park and the CC parking lot via of Castillo. This year they will be going down Garden. Quite a mess.

Of course we'll survive. It wouldn't bother me to ride down Garden. Once I rode from San Ysidro Stables in Montecito to be in the parade and rode back after.
