The parking lot near the old fairgrounds in South Park will be demolished and replaced.
The lot near the fairgrounds at intersection of Brownsville Road and Corrigan Drive will be closed beginning Tuesday (June 22).
Ceremonial groundbreaking for the $2.4 million project will take place in July.
It's expected to be closed until late 2021.
Allegheny County Public Works said the closure could affect parking for summer concerts series at the park.
The new lot will be permeable in an effort to reduce stormwater runoff.
