Sacramento's Space Needle?

Sacramentan Walter Horsting is proposing a new icon for California's capital city, The Golden Spike. Here are his words:

The Golden Spike Landmark
Sacramento needs a landmark that reflects the history of the Sacramento Region. St. Louis has the Arch: Gateway to the West and Seattle has the Space Needle. What symbol can capture the historical foundations of Sacramento: The Gold Rush and the building of the Transcontinental Railroad; other than the Golden Spike?

How to pay for it?
My plan is simply to lobby the development community, city, state and building owners to make our next great office tower in the shape and color of The Golden Spike. All it would take is a project like the Capitol West End Project to build its 1.5 to 1.8 million square feet vertically to have the scale of the Golden Spike. It is Greener to build vertically.

Where to place it?
Several sites come to mind: The current Sacramento Depot; The former site of the Towers; West Sacramento on the Western end of the Capitol Mall. If the city and state are serious about transit, green building and cutting commute times and cost: I would place it near the new intermodal station for all the state office workers to use transit.
