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
