On Tuesday, after we reported SDOT‘s long-awaited answer to the question “when will the new 1st Avenue South ramp from the westbound Spokane Street Viaduct open?” (see the story here), three questions emerged in the comment section. Below, the answers, via SDOT’s Rick Sheridan:
Q: When SDOT shifts traffic to the new structure to repave the existing one, will we lose the eastbound 4th ave on-ramp?
A: When we repair and then resurface the deck of the old structure, closures of the eastbound off-ramps will be required to safely facilitate the work. This will impact the eastbound First Avenue S off-ramp and the new Fourth Avenue S off-ramp, though we will not close both at the same time. One of the two eastbound off-ramps will be available for use during that work.
Q: Is the much-later ramp completion going to result in any kind of penalty for the contractor, or was that not a component of the contract?
A: No. This is because major utility relocation work necessary for the ramp’s construction was outside of our control. The delay, however, does have financial implications for the contractor as a longer project phase incurs more costs.
Q: Who’s the “steel subcontractor”?
A: The subcontractor is Stinger Steel from Montana.
The original report is here. As noted, SDOT originally had said the ramp would take at least 16 months to build, but if the “not fully open until July” holds true, that will be 26 months. Last February, concrete work on the ramp had to be torn out and redone because of an alignment error, but at the time, SDOT said that wouldn’t affect the project schedule.
