A chipmaker will send temporary workers to Phoenix to help build a massive factory while the state and city pledge to extend a major road near the site.

Taiwan Semiconductor Manufacturing Company, known as TSMC, plans to send hundreds of temporary workers to Arizona to speed up construction in far north Phoenix. The chip fabrication facility is scheduled to be running by 2024, but Asian media first reported construction has fallen behind partly because there aren’t enough U.S. workers with the expertise for certain construction.

Meanwhile, the Phoenix City Council recently approved a plan to extend a critical roadway near TSMC’s site. The $10.5 million project to extend 43rd Avenue from Dove Valley Road to the Carefree Highway will be covered using city and state funds.

Phoenix’s Street Transportation Department provided the following statement to KJZZ News:

“The City of Phoenix will be the lead for construction of the 43rd Avenue extension, to ensure that it is built to city requirements. There is no timetable yet for when the design or construction would begin, as the eventual alinement will be driven by future development needs in that area."

TSMC has said it will invest more than $40 billion to build two fabrication plants in Phoenix and expects to get billions in tax credits under the CHIPS Act.
