Cathedral Oaks Road Detour

A detour is in place for Cathedral Oaks Road around the closure between Calle Real and Winchester Circle. The detour will route drivers down Calle Real and Winchester Canyon Road to the opposite end of the closed road section. The detour is shown in the map below.

The City closed Cathedral Oaks Road on February 4, 2024, between Winchester Circle and Calle Real. Heavy rains and storm runoff have heavily damaged both the slopes and the 40-foot high crib walls supporting Cathedral Oaks Road and the adjacent bike path. A Crib Wall is a type of large-scale retaining wall that retains an earthen slope. This damage raised concerns over the integrity of the roadway and thus prompted the closure of this portion of Cathedral Oaks Road.

Initial inspections have been completed by the City’s engineers. Pending a determination of the extent of damage, costs of repair, and available funding, this portion of Cathedral Oaks Road will remain closed until deemed safe for traffic. The City is in the process of hiring an engineering firm to design the reconstruction of the slope and new retaining walls. City staff understand the value of opening this portion of Cathedral Oaks and are dedicated to delivering repairs as quickly as possible. We appreciate your patience as the City addresses this costly and complex project.
