The "soft opening" of the Big Four Bridge, which is being converted to a pedestrian and bicycle pathway, will be delayed until late January or early February, according to a news release sent by the Louisville Waterfront Development Corporation.The issue, said the release, is "due to a holdup in the fabrication of the railings for the bridge. The balance of the railings for the bridge will not be received until mid-January, and installation could take several weeks. As safety is of utmost importance, the bridge cannot be opened until all railings are installed."When opened in late January/early February, the bridge will be complete with railings, lights, benches, signage, and the simulated rail bed down the middle, the release said.A soft opening was expected by the end of this year.
