Delivery and assembly of modular building will bring parking, traffic and noise impacts to Capitol Campus

OLYMPIA - A modular building that will provide temporary office space on the Capitol Campus during projects related to Legislative Campus Modernization (LCM) will be delivered and assembled in the Mansion Parking Lot starting next week. There will be parking, traffic and noise impacts.

LCM involves a series of projects located on different sites on the West Capitol Campus. The project will address space needs of legislative agencies and critical issues with the Irving R. Newhouse, Joel M. Pritchard and John L. O’Brien buildings.

Initially, the Legislative Modular Building will provide temporary office space for legislators and their staff who occupy the Irving. R Newhouse Building, which will be replaced as part of LCM. After the Newhouse Building is replaced, the Pritchard and O’Brien buildings will be renovated. Staff from those buildings will move into the modular building during that work. The modular building is expected to remain on the Capitol Campus for six to eight years.


Starting on Nov. 4: 16 building modules will be delivered and staged.

Starting on Nov. 7: a 300-ton, 150-foot-tall crane will be used to fit the pieces together.

All work is weather dependent.


Parking: The Mansion Lot will be closed Nov. 1 to 18. The North and South Diagonals and the Visitor Information Center Parking Lot may be busier than usual. Visitor parking options can be found on the Capitol Campus Interactive Map.


  • Pleasant Lane will be limited to one-way access (northbound).
  • 12th Avenue Southwest will be intermittently closed from Water Street to Pleasant Lane during module deliveries.
  • Pleasant Lane will be closed Saturday, Nov. 5, during electrical work.
  • Alternate routes will be clearly marked. General construction noise can be expected between Nov. 1 and 18.
