A major landslide was captured on video narrowly missing piers for a viaduct under construction at the Yusufeli Dam site in Artvin, Turkey. The slide appears to be on an engineered cut slope benched into […]
I stumbled across a nice interview of Dan Brown, a recognized deep foundation expert and founder of Dan Brown and Associates, in a back issue of Pile Buck magazine. He discussed some of the large […]
Check out this proposed bridge in China’s Zhangjiajie National Forest. It has a span of 1,200 feet and is over 1,300 feet off the ground. The majestic landscape was reportedly the inspiration for the Halleluja […]
The City of North Haven is located on an island off the coast of Maine. This town was faced with a unique challenge when a bridge needed replacing. Looking for an economical option, designers decided on a Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS). This solution allowed the town and DOT to re-use an existing bridge pier, beat the construction deadlines, and provide a modern bridge solution for this small town.

Work has begun to construct temporary piers to support the I-43 Leo Frigo Bridge. Pier 22 of the bridge settled approximately 2.5 feet in late September/early October. The new piers are being constructed by Lunda […]
Pier 22 of the Leo Frigo Bridge settled 22 to 27 inches last week causing a 400 foot long segment of the bridge to sag dramatically, forcing the closure of the bridge. There were no […]
An 11-foot diameter limestone core has become a ‘geotechnical monument’ of sorts according to the good folks at Dan Brown and Associates. DBA was the geotechnical designer for a new bridge carrying I-70 over the […]
70 boreholes were completed as well as 7 load test piles to characterize the geotechnical conditions for this well known bridge spanning the Hudson River in New York. No significant surprises were encountered compared to […]
UK structural and geotechnical engineers have long used the British Standard codes for design of railroad bridges. Those days are now gone as all rail structures are required to use the Eurocode. This article is […]
TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 177: Evaluation of Bridge Scour Research: Geomorphic Processes and Predictions explores the impact of long-term aggradation and degradation, and lateral river channel migration, on highway structures. […]
