Jefferson Parkway Construction Closure: Spinosa to Abelard

Starting the week of July 9, the Jefferson Parkway work area shifted east; see details below. Watch for signage changes and plan to use alternate routes. 

Construction schedules are always subject to change due to weather, availability of crews, materials or equipment, and other variables.

Spinosa to Abelard closure details

  • Neighbors who live on Spinosa, Mountain View Lane, and Creekside Terrace have access to a segment of Jefferson Parkway from the direction of Westlake and Kingsgate.

  • Neighbors who live on Abelard have access to a segment of Jefferson Parkway from the direction of Kerr Parkway. (Also, Abelard will remain reachable via Kingsgate and Aquinas.)

  • The western intersection of Cervantes and Jefferson Parkway is closed. The eastern intersection, nearest Kerr Parkway, will remain open.

Later this summer

The work zone and closure points will again shift east — spanning from Abelard Street to just west of Kerr Parkway. The contractor will work with neighbors on streets that have limited access.

Crews will return to each area for final top-paving and striping.

Days, hours and detours

Crews generally will work Monday through Friday 7 a.m. to 6 p.m., and some Saturdays. Paving days may have later hours, if needed.

However, when the road has been ground down, full road closures (sometimes called “hard” closures) with detours will be in place 24 hours per day, seven days per week. During a full closure, everyone (including residents) must follow the detour routes or find another route.

  • Only residents who can’t reach their homes any other way are admitted through the closure, on specific access routes.
  • Residents on streets accessible at only one location from Jefferson Parkway will have a specific access route around the closure (either from the west or east), depending on the location of the work zone. Watch for signage changes and follow any instructions from the contractor. 


Pavement grinding will make the road unsafe and unfit for travel within the closure during all hours. Follow all traffic-control signage and avoid active construction areas, for the safety of all. 


Schedule: May – September 2018 (major work June – August while school is on break)

Project: Includes reconstruction of the Jefferson Parkway road surface from Westlake Drive to Kerr Parkway (see the map), curb ramp replacements, new signs, and striping. This is a pavement rehabilitation project and does not include sidewalk.

Traffic impact: Jefferson Parkway will be closed in phases. Watch for detours over the summer. Access will be coordinated for neighbors who must use Jefferson Parkway.
