Downtown Oklahoma City garage connection would cost $1.6 million, according to 2017 estimate, for a tunnel or skyway
An early estimate of the cost to connect the Santa Fe garage by tunnel or skyway to a new parking garage in west Bricktown is $1.6 million.
The city is to build a pedestrian link between the structures under terms of the agreements to sell the Santa Fe garage and develop the Bricktown garage.
The city council agreed to a framework for completing the transactions last week, and the Central Oklahoma Transportation and Parking Authority board endorsed that decision on Monday.
Crossing beneath the BNSF Railway viaduct and E.K. Gaylord Boulevard, or overhead, the passageway would protect pedestrians from the weather.
Public Works Director Eric Wenger said the $1.6 million figure was calculated in April 2017 as part of a conceptual study.
"Should the project move forward," he said, "we would move from a conceptual to a preliminary design, and re-look at the cost estimates."
Wenger said some inflation in construction costs is to be expected and "we would also look at additional project details."
BancFirst Corp. and Continental Resources are buying the Santa Fe garage, the city's largest municipal garage, for $22.5 million.
Bricktown Parking Investors and BancFirst are buying a surface lot, currently leased to Bricktown developer Don Karchmer, for the new west Bricktown garage.
Preliminary sales price for the Bricktown property is $1.4 million.
The transactions are intended to secure long-term parking for Continental Resources and the Cotter Ranch Tower, formerly the Liberty Bank tower.
BancFirst is buying the Cotter Ranch Tower for its headquarters.
Proceeds from sale of the Santa Fe garage will go toward development of a new municipal garage in the MAPS 3 convention center complex.
Built in the early 1970s, the Santa Fe garage has seven levels and 1,518 spaces. It is the largest of five municipal garages.
The city spent $900,000 in the past two years modernizing the elevators and another $100,000 on payment- and access-system upgrades.
While the garage is near the end of its original 50-year life expectancy, an appraisal notes a "very conscientious maintenance program" has extended the structure's economic viability.
The appraisal estimates the Santa Fe garage could remain in service another 20 years.
BancFirst and Continental Resources agreed to pay a little under $15,000 per space for the Santa Fe garage.
A September 2016 estimate to build the 865-space, $35.2 million parking garage for the MAPS 3 convention center and convention center hotel was $40,700 per space.
By comparison, a 2,125-space garage planned at Will Rogers World Airport would cost $22,700 per space, according to a 2016 estimate.
