Pittsburgh - North Shore: Rachel Carson Bridge
Image by wallyg
The Rachel Carson Bridge, also known as the Ninth Street Bridge, spans 840 feet across the Allegheny River, connecting the North Shore and the Central Business District in downtown Pittsburgh. Originally opened on November 26, 1926, it was renamed after Pittsburgh native and naturalist, Rachel Carson, on Earth Day, April 22, 2006. The bridge was built from 1925 to 1928 by architect Stanley L. Roush and engineers Vernon R. Covell, H. E. Dodge, Alfred D. Nutter and T. J. Wilkerson of the Allegheny County Department of Public Works.
The bridge was renamed after years of lobbying by Esther Barazzone, president of Chatham University--Carson's alma mater, which was known as the Pennsylvania College for Women when she graduated in 1929. Rachel Carson (1907 -1964) was was born 18 miles up the Allegheney River in a farmhouse in Springdale, now the Rachel Carson Homestead. She began her career as a marine a biologist in the U.S. Bureau of Fisheries and achieved financial success and fame as a nature writer, with her 1951 bestseller, The Sea Around Us. Along with her next bestseller, The Edge of the Sea, and the first book, Under the Sea Wind, she explored the whole of ocean life, from the shores to the surface to the deep sea. In the late 1950s, Carson turned her attention to conservation and the environmental problems caused by synthetic pesticides which culminated in 1962's Silent Spring, which led to a nationwide ban on DDT and other pesticides and inspired a grassroots environmental movement that led to the creation of the Environmental Protection Agency.
Along with the Andy Warhol Bridge and the Roberto Clemente Bridge, it is one of the "Three Sisters Bridges," three parallel self-anchored suspension bridges crossing the Allegheney. They were the first self-anchored bridges built in the United States. The Municipal Art Commission had mandated the bridges all be suspension, but the site conditions didn't allow for typical anchorages. The unusual self-anchored design features heavy anchorages to hold the cable ends and rigid towers to hold the ends apart. The deck girders were originally painted green with the remaining superstructure aluminum grey, but today, like most downtown Pittsburgh river bridges, it is painted yellow.
The Ninth Street Bridge was designated a landmark by the Pittsburgh History and Landmarks Foundation Historic Landmark in 1988.

Constantine Historic Commercial District, Constantine, Saint Joseph County
Image by MI SHPO
Listed on the National Register of Historic Places on September 17, 1985, the Constantine Historic Commercial District comprises five acres in the original, two-block core of the Village of Constantine's historic and contemporary central business district. The district contains thirty-four commercial and residential structures, the majority of which represent nicely preserved examples of mid-nineteenth to early twentieth century Greek Revival and Italianate styles. The commercial buildings are between one and three stories in height. The Greek revival structures are covered in asphalt shingle, aluminum siding, and painted clapboard with rectangular facade openings, gable ends with returns, and simple classical lines. The dominant Italianate brick blocks display elaborate bracketed cornices, round or segmental-arched windows with hoodmolds or other decorative accents, central roofline pediments, pilastered entry bays, transoms or fanlights, and large display windows.
The Constantine Historic Commercial District derives its significance from both historic and architectural features. Founded in 1828, the Village of Constantine soon became a major regional port for shipping agricultural products east and receiving return shipments for local merchants. Among the important persons associated with Constantine's economic development was former Michigan governor and state senator John S. Barry (1842-1846, 1850-1851), whose river trade and mercantile interests centered in the village. Several Greek Revival structures remain from the period, among them Barry's original warehouse. The prosperity established during Constantine's river trade era carried over into the 1870s when local residents financed a number of handsomely detailed Italianate commercial blocks. Despite alterations to street level facades, Constantine's commercial center remains remarkable for the elegance and historic character of its nineteenth and early twentieth century downtown structures.
