RJW Finger Joints are a simplistic design with no moving parts that are designed to accommodate any bridge deck expansion joint movement.

Finger Joints are cantilevered or simply supported steel tooth expansion joints. They are comprised of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths.   RJW Finger Joints are used to provide support to vehicles as they travel across bridge expansion joint openings. They create an effective seal at the joint opening, preventing water and deleterious materials from contacting the steel support girders and bearings below.

RWJ Finger Joints were installed on the Ohio River Bridge

Why RJW Finger Joints?

The maintenance crews like them because they are designed for ease of maintenance with a small crew and minimal lane closure time. They can be fabricated to meet bridge deck skews and can be supplied with post tensioned anchors into concrete headers, cast into concrete blockouts, or bolted to existing steel members

Bridge owners like them because they can be supplied with post tensioned anchors into concrete headers, cast into concrete blockouts, or bolted to existing steel members and the joints will last the life of the bridge under normal circumstances

Communities prefer them because they provide a smooth transition for vehicular traffic, resulting in low noise
