Progress continues on the Wonder World Drive extension, according to San Marcos city officials.
Much of the action now is taking place at Purgatory Creek Bridge, where the bridge decks presently are being poured. Four of the seven decks have been completed. About 60 percent of the project has been asphaulted.
Phases 2 and 3 are underway on the east and west ends of the project. Construction at RR 12 is expected to last for six-eight weeks, while work on the Hunter Road end will take another two-four weeks.
As of Jan. 5, the project is 412 days into a 617 calendar day schedule.
Each segment of Purgatory Creek Bridge involved three spans, and each span is 110 feet long. The typical segment requires 400-480 cubic yards of concrete, which calls for 40-50 concrete truck deliveries. In comparison, an 80-pound bag of Quikcrete yields 0.6 cubic feet of concrete, meaning it would take 18,000 bags to complete each pour.Email | Print
