Thomas Viaduct Railroad Bridge
ASCE National Historic Civil Engineering Landmark
The Thomas Viaduct Railroad Bridge in Relay Maryland has been designated as a National Historic Landmark by the American Society of Civil Engineers (ASCE).
We plan to mount the plaque on a boulder (similar to adjacent photo). We have located a boulder of the same granite that was used to construct the viaduct at the Woodstock Quarry. The plaque & boulder will be placed near the contact station along the Park Entrance Road in the Avalon Area of Patapsco State Park. The plaque will be placed in the landscaped beds, just behind two other markers, one of which is about the Viaduct. Our plaque will add context and significance to the viaduct by noting its historical and engineering significance. The location will be visible to all who visit the park.
The Maryland Section of the American Society of Civil Engineers is sponsoring this project. We are raising funds for the pedestal, mounting of the plaque, retention of a contractor, and for delivery. We expect that we will schedule and conduct an unveiling ceremony after the plaque is installed sometime in 2023. We are encouraging the local ASCE members, and railroad organizations, companies, and individuals to join us as we permanently honor and designate the Thomas Viaduct. We are soliciting funds to pay for:
Casting the plaque
Hauling the stone
Mounting the plaque to the stone
Placing the stone at the Park Site
Costs for the unveiling
Our fundraising goal is $3,500 to cover these expenses. Please consider a donation to help make the plaque a reality! We also invite your suggestions and participation as we plan the ceremony. All organizations that provide donations will be displayed and invited to the ceremony.
Please submit your donation no later than February 28, 2023. ASCE is a 501 (c) 3 organization, so your donation may be tax deductible.
Thank you for your consideration of this effort to honor the Thomas Viaduct.
