TYPE OF CONSTRUCTION / DESIGN:
YEAR ERECTED / ENGINEER:
In 1915-17, the City-County Building was constructed in the block bounded by Grant St, Forbes Av, Ross St and Fourth Av. In the year following its completion, a tunnel was dug under Forbes Av to link the basements of this building with the adjacent Allegheny County Courthouse.
As other related buildings were constructed in adjacent blocks, a network of tunnels was created -- with the City-County Building as the hub. The Grant Building by Henry Hornbostel and Eric Fisher Wood rose opposite Fourth Av in 1927-30. The County Office Building by Stanley L. Roush was built across Ross St in 1929-31.
