Humboldt 101 Drainage North
Caltrans proposes to rehabilitate approximately 51 drainage systems at various locations on U.S. Highway 101 in Humboldt County from north of the Rio Dell area to the Del Norte County line. Additional traffic management upgrades are also planned.
The project’s identified drainage systems need repairs, replacement or capacity enhancements. The work is needed to repair failed and deteriorated drainage systems to prevent potential roadway damage resulting from drainage system failures. Traffic-management upgrades include electrical upgrades and improves changeable message signs.
Construction is anticipated to begin in the summer of 2025 and end in early 2028.
Traffic impacts will be minimal. Lane closures will be required at several locations with 5-minute delays due to one-way traffic control.
