Description

Metro would like to reconstruct the Union Station Tunnel with a reduced cross section that more closely aligns with the operating alignment. All areas outside the reconstructed tunnel will be closed off and entirely filled. A concrete culvert at the west end of the tunnel will remain in place and does not require any structural rehabilitation. See the Scope of Work Section for further information.
