WALNUT CREEK -- The tall white building at 1500 Newell Ave. downtown -- once known as "the Peace Building" -- is being demolished over the next several weeks. Internal demolition was underway this week, with demolition of the exterior set to begin Monday, Nov. 5 and finish before Thanksgiving.

To ensure the public's safety during the exterior demolition, there will be significant lane closures around the Main Street/Newell Avenue intersection starting Nov. 5.

Specific planned closures include:

  • Main Street southbound will be closed between Broadway Plaza and Newell Avenue.

  • Newell Avenue eastbound between the Newell Promenade entrance and Main Street will be closed, except for one lane that will be right-turn only onto South Main Street.

  • Newell Avenue westbound will be closed between Main Street and the Newell Promenade entrance.

    The Kaiser Permanente Medical Center garage entrance on Newell Avenue will remain open. Also, Newell Promenade shops on Newell between Main Street and California Boulevard will remain open.

    Lane closures will be in effect between 7 a.m. and 6 p.m. Monday through Friday. Changeable message signs are now in place to alert drivers to the closures.
