Expansion Joints

Accommodate naturally occurring movement with high-quality, long-lasting expansion joints

RJW Finger Joints

RJW Finger Joints are cantilevered or simply supported steel tooth bridge expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from three feet to full roadway widths. Choose RJW Finger Joints for any bridge deck expansion joint movement.

Designed for Any Application

The simplistic design of RJW bridge finger joints, which have no moving parts, can accommodate any bridge deck expansion joint movement. These expansion joints are comprised of pairs of independent elements with parallel steel teeth. The tooth joints support vehicles as they travel across expansion joint openings.

The Right Size

RJ Watson offers finger joints in sizes ranging from three feet to full roadway widths.

RJW Finger Joints effectively seal the joint opening against water and debris, protecting the steel support girders and bearings below.

Choose RJW Finger Joints

RJW finger expansion joints offer benefits to bridge owners, maintenance crews and local residents.

  • RJW Finger Joints can be supplied with post-tensioned anchors into concrete headers, cast into concrete blockouts or bolted to existing steel members. RJW Finger joints are designed to last the life of the bridge under normal circumstances.
  • Maintenance can be completed with a small crew and minimal lane closure time. Designing and building with RJW bridge finger joints means smooth transitions for vehicles, resulting in low noise.
