White River Concrete Arch Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1930-1939 DateCreated: 1930 White River Cotter State: AR Zip: 72626 Country: USA Website: http://www.asce.org/Project/White-River-Concrete-Arch-Bridge/ Creator: Marsh, James Barney

When this 1,850-foot concrete-arch highway bridge was built on the White River in a remote region of northern Arkansas - prior to the construction of upriver, flood-control dams - flash floods occurred frequently, sometimes causing the water to rise as much as one foot per hour. Construction under these conditions presented a clear danger, so project managers specified both a design and an innovative construction method appropriate to the problem of building across a perilous stretch of unpredictable river.

The Lake Moeris Quarry Road, in the Faiyum District of Eygpt, is the oldest road in the world of which a considerable part of its original pavement is still preserved. This road was used to help transport the heavy blocks of basalt from the quarry 43 miles southwest of Cairo to the royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. The road covered the 7.5 miles from the quarry to Lake Moeris which, at that time, was 66 ft above sea level.

When Governor James Grant arrived in the newly acquired British colony of East Florida in 1764, he found it devoid of settlers. To increase both the population and commerce with the 13 colonies to the north, he commanded that a road be built from his provincial capital of St. Augustine to Ft. Barrington, Georgia.

When a new road bridge was constructed alongside it, plans were made to demolish the Conwy Suspension Bridge. There was a national outcry and, since 1958, the bridge has been in the care of the National Trust and closed to vehicular traffic.

Montgomery Bell's Tunnel
Society: ASCE Main Category: Civil Sub Category: Tunnels Era: 1800-1829 DateCreated: 1818 Harpeth River State Park Kingston Springs State: TN Zip: 37082 Country: USA Website: http://www.asce.org/Project/Montgomery-Bell-s-Tunnel/ Creator: Bell, Montgomery

Montogomery Bell was a land developer and iron maker who purchased the Harpeth Narrows site to expand his industrial empire - which ultimately consisted of 14 iron blast furnaces throughout middle Tennessee.

The Harpeth River makes a tight bend around a steep limestone ridge, losing 17 feet of elevation in a run of 5 1/2 miles. Bell excavated a tunnel through the limestone ridge, creating a shortcut for the river. The hydropower derived from this drop in elevation was used to drive the Patterson Iron Works built by Bell.
