Demolition of the R.H. Thomson "ramps to nowhere"

10/15/2014 to 10/18/2014

Beginning the week of Oct. 13, crews and cranes will remove portions of the R.H. Thomson "ramps to nowhere." This work, which will take many months to complete, will restore the Arboretum and make it an even more inviting open space for local and regional users.

Noise: Nearby residents may hear the sounds of construction equipment sawing through the ramps to take portions by crane and flexifloat to land. Traffic: Some demolition work will require highway and/or ramp closures. Check the SR 520 Orange Page for the latest information on closures.
