| 摘要： | The construction of Interstate 579 (1-579) through Pittsburgh, Pa., more than 60 years ago separated the Hill District from the downtown. With the help of federal grant money from the Transportation Investment Generating Economic Recovery program, the Urban Open Space Cap project creates a new modern park with room for outdoor events and reconnects the disenfranchised district to the city's economic core. The 1-579 project functions as a "cap" over the interstate that provides a walkable link from the Hill District to the downtown. The new park includes art installations, story walls, outdoor classroom space, and an amphitheater, as well as bike and pedestrian pathways. After evaluating several options, the design team selected adjacent precast concrete box beams for several reasons: The beams are strong enough to support the unique park loading, including up to 5 ft of soil. Locally available bridge elements were economical. And precast concrete box beams were ideal for the urban site because they could be delivered with minimal site disturbance and lifted from adjacent parcels to minimize the impact of the construction on the highway below. |
