  • Full Nighttime Closure of Moorpark Road - Nighttime full closures are scheduled for all lanes of Moorpark Road at the US 101 freeway. Moorpark Road will be closed to through traffic underneath the 101 freeway for four consecutive nights, between 9 p.m. and 6 a.m., Monday, Oct. 12 through Thursday, Oct. 15. Crews will be conducting work at the Moorpark Road undercrossing as part of the freeway widening. Detour Route: Moorpark Road will be closed to all through traffic underneath the 101 freeway; it is recommended that motorists use Lynn Road or Rancho Road as an alternate.
  • TENTATIVE Weekend Full Closure - Northbound US 101 Hampshire Road On-Ramp,
    8 p.m. Friday, Oct. 16 through  6 a.m. Monday, Oct. 19 - An extended weekend closure of northbound US 101 on-ramp at Hampshire Road is tentatively scheduled from 8 p.m. Friday, Oct. 16 through 6 a.m. Monday, Oct. 19, as crews work to realign the on-ramp as part of the freeway widening project. Please refer to the project Google map for up-to-date information regarding this closure.  DETOUR: During the ramp closure, motorists should use the northbound US 101 on-ramp at Rancho Road. For motorists traveling south on Hampshire Road, use the southbound US 101 on-ramp, exit Westlake Boulevard, turn left on Westlake Boulevard and enter the northbound US 101 using the loop on-ramp.
  • DISCLAIMER: Please be advised, dates and times are subject to change due to unforeseen operational factors or inclement weather.

    Bridge Widening Underway at Hampshire Road, Conejo School Road & Moorpark Road.
    To accommodate the widening of the 101 Freeway, crews demolished a portion of the overcrossings at Hampshire Road, Conejo School Road and Moorpark Road (northbound side only). Now that demolition activity is done, one northbound lane at Hampshire Road and Moorpark Road will remain closed for an extended period of time, allowing crews to widen the 101 freeway overcrossings.

    Long-Term Construction Impacts
    While most construction activity will take place at night or during off-peak hours, lanes have been reduced in a few locations in order to facilitate construction activity. Intermittent nighttime lane closures on the northbound US 101 and surrounding on- and off-ramps may be required over the next few weeks, although no closures are currently scheduled. To avoid congestion and minimize delays related to this work, consider alternative routes and allow extra time to reach your destination if your trip involves the following routes:

    • Northbound US 101 Connector to Northbound SR-23 reduced to one lane, 24/7.
    • Northbound Hampshire Road to Northbound US 101 on-ramp has been reduced to one left turn lane, 24/7
    • Northbound Moorpark Road at US 101 undercrossing, extended lane reduction, 24/7
    • Northbound Hampshire Road at US 101 undercrossing, extended lane reduction, 24/7
