Bridging the Gap

Workers core-drilled and installed 38 reinforcement anchors to increase the capacity of the 180-year-old Aldie Bridge in Virginia.

Of the 1778 masonry bridges in the U.S., more than half are either functionally obsolete or deficient.

Many of the 1778 masonry bridges in the U.S are concentrated in the Northeast and Mid-Atlantic.

The ends of the arch of the 152-year-old Cattle Pass were unraveling because the exposed brickwork at the ends collapsed.

Workers rebuilt all of the loose or missing brickwork in the intrados using existing brick to limit differential moisture growth where possible.

The completed arch restoration.

Kirkwood Masonry in Missouri has developed its own niche by building small masonry bridges on golf courses, including this one at Greenbriar Hills Country Club in Kirkwood, Mo.
