Lincoln, Nebraska, boasts the Nation's first heated pedestrian bridge. The 10th Street pedestrian viaduct is a precast, prestressed, post-tensioned concrete superstructure with a 165 mm (6.5 in) cast-in-place deck. This article describes this one-of-a-kind pedestrian crossing, addressing in detail the deck heating system, its installation and construction, and evaluation and monitoring of the system. As the premier project of this type in the United States, heating system components will be monitored and analyzed carefully for implication in future designs. |
