Loop 101 Noise Wall

March 2012 - You can see construction of the sound walls really taking shape. The current construction schedule shows completion of both of the Loop 101 sounds walls between Via Linda and Camelback Walk Wash in the next few weeks -- by mid-May.


May 2011 - The Arizona Department of Transportation will begin replacing the Loop 101 sound walls between Via Linda and Camelback Walk Wash in the next few weeks.  Crews will work 8 to 10 hour shifts beginning at 6 a.m. Monday through Friday.  There may be occasional weekend or evening work as needed.

Construction should be completed by the end of the year.

Only a small section of the entire sound walls in the area will be replaced to accommodate the addition of a general purpose lane in the future. (See project area map to right.) 

Click on the "play video" buttons on the right side of the page to see video of the affected walls on both the freeway and multi-use path.

The new sounds walls will be higher to provide for additional freeway noise mitigation to nearby residents.

During construction, portions of the Pima and Camelback Walk multi-use paths will be closed. Detour signs will be clearly marked throughout the corridor.

Scottsdale worked closely with residents, ADOT, the Maricopa Association of Governments and Scottsdale Public Art, including coordinating with the original artist and landscape architect for the existing walls, to develop a plan to replace the section of artist-designed sound wall that runs from just south of Via Linda to the northern bank of the Camelback Walk Wash.

The entire segment that is proposed for replacement is approximately 1,757 feet (0.33 miles) and will be paid for out of Proposition 400 funds.

This web page is dedicated to providing the details of the project status, reasons for replacing the wall, the coordination between Transportation staff, ADOT, MAG, Scottsdale Public Art, and neighboring residents, and the general public outreach that has occurred. 


Project Facts:

  • As part of the Regional Transportation Plan adopted by the Maricopa Association of Governments in 2003, funding was included for additional freeway noise mitigation along freeways that were constructed as part of the region’s 1985 freeway plan.  The resources to implement this noise mitigation plan were approved through the passage of Proposition 400 in November 2004.
  • In June 2007, the city requested that two neighborhoods on the west side of Loop 101, the Sands McCormick area near Via Linda and the Astoria/Greenstone area near Cactus Road, be given consideration for additional freeway noise mitigation using these funds. These two locations, along with eight others throughout the metropolitan area, were approved by MAG for participation in this program. The ten-wall project is nearing design completion and is scheduled to bid in the next several months at an estimated cost of $26 million.
  • Scottsdale worked closely with residents, ADOT, MAG and Scottsdale Public Art, including coordination with the original artist and landscape architect for the Loop 101, to develop a plan to replace the section of artist-designed sound wall that runs from just south of Via Linda to the northern bank of the Camelback Walk Wash.
  • Only a small section of the art walls (just under 10% of the total length, and a lesser amount of the total square footage) located in Scottsdale from Via Linda to Raintree Drive will be replaced to accommodate the future addition of a general purpose lane and to increase the height of the wall for additional freeway noise mitigation. L101(2)
    • The cumulative length of the art walls located between Via Linda and Raintree Drive is approximately 17,700 feet (approximately 3 miles long).
    • 1757 feet (9.9%) will be affected by this project.
      • Estimated construction costs to replace the 1,757 feet of wall, widen two bridges, and relocate a sewer line and path are approximately $5.5 million dollars.  This includes replacing the wall with aesthetic features, at an estimated cost of $600,000, that blend into the art that will remain.
      • Fully replicating the existing artwork on the new wall has been estimated by ADOT staff to cost approximately $2 million.
  • In 2014, ADOT is scheduled to begin construction of an additional travel lane in each direction on Loop 101 from Shea Boulevard south to Loop 202, which, based on the concept design recently prepared by ADOT, will require the relocation of the section of art wall on the west side of the freeway in the Via Linda area to its final placement for the built-out freeway.
    • The section of wall being replaced (see attached photos) is the lowest in height in the area, ranging from 6 to 12 feet.  The new wall will range between 12 and 20 feet.

Public Outreach Efforts:

  • Coordination meetings with ADOT and Transportation staff began in August of 2009. 
  • Transportation staff contacted HOA presidents adjacent to both walls either by phone, e-mail or letter, asking for input and if an additional meeting to address their concerns was needed.  No responses to these inquiries were provided from residents adjacent to the art wall.
  • Transportation staff began coordination with Scottsdale Public Art on the project
  • ADOT contacted each city to work with them on public meetings regarding the relocation of sound walls throughout Maricopa County.  Scottsdale had two walls, the portion of art wall located just south of Via Linda that runs to the northern edge of Camelback Walk Wash and the other just north of Cactus Road.
  • ADOT sent flyers to residents in both neighborhoods inviting them to a public meeting and to gather input. The public meeting for Scottsdale residents was held on November 16, 2009 at the Mustang Library.
  • Several residents from the neighborhood with the art wall did attend the public meeting, but no major concerns were discussed over the relocation and replacement of this wall.
  • Scottsdale worked with Scottsdale Public Art, ADOT and the original artist and landscape architect to develop a compromise regarding the aesthetic component of the replacement wall.

City staff is continuing to meet with representatives from ADOT and Scottsdale Public Art to see if the impacts of the freeway widening/noise wall project can be further mitigated.
