HISTORIC PRESERVATION
UNDER $1 MILLION
EASTERN HIGHWAY SPECIALISTS
Rehabilitation of Ashland Covered Bridge 1-118
The Eastern Highway Specialists team successfully preserved the historic timber-covered bridge with remarkable skilled labor, construction creativity, and speed. The project’s necessary improvements to the timber lattice structure were completed in place over the flowing creek, adding temporary shoring and access challenges. Precision timber carpentry skills were required to replace damaged timbers with traditional heavy-timber trunnel construction methods. Construction excellence for this creative and challenging project was achieved four weeks ahead of schedule.

INFRASTRUCTURE CONSTRUCTION OVER $10 MILLION
RICHARD E. PIERSON CONSTRUCTION CO., INC. (REP) BR3-155 N&S on SR1 over Broadkill River
This $12 million project for DelDOT involved the removal and replacement of the twin bridges’ five spans of superstructure and rehabilitation of their substructures, consisting of two abutments and
four piers each — all while maintaining traffic and under a tight schedule. This project utilized a concept called “Accelerated Bridge Construction” or “ABC.” It places a huge emphasis on utilizing precast elements in the design and subsequent construction of the bridge. Considering this project was located on one
of Delaware’s busiest corridors, and an extremely aggressive project schedule was imposed so as not
to overly impact traffic, this project became an ideal candidate for ABC. Through the collaborative efforts of the entire project team, it was delivered on schedule and on budget. The ingenuity of REP and the utilization of its marine and crane fleet enabled the company
to construct this challenging project and deliver to DelDOT a quality result, extending the life of this structure by at least another 50 years.
