PROJECT NAME: I-84 Bridge and Approach Paving MP 88.04 & 89.89

SCOPE OF WORK:

Fifteen Mile Creek Bridge (East & West bound lanes): work includes 2-inch depth cold plane pavement removal of bridge approach and impact panel wearing courses up to expansion joints at bridge deck, inlay of HMAC, and Control Joint installation where new approach asphalt meets existing roadway wearing course. Existing expansion joints at bridge ends are to remain, contractor to utilize appropriate mill to preserve the existing expansion joints.

Big Eddy Bridge (West bound only): work includes cold plane pavement removal of bridge approach and bridge deck wearing courses, bridge deck membrane, expansion joints, new rolled waterproof membrane, inlay of HMAC, installation of two new full width precompressed foam silicone joint seals at the bridge deck, same location as existing per Detail 3138, two new full width asphaltic plug joint seals at bridge deck ends per standard drawing BR 157.

The work also includes performing all traffic control, and temporary pavement markers at both locations.

WORK LOCATION: The work is on I-84 near The Dalles at Fifteen Mile Creek Bridge #20875, MP88.04, and Big Eddy Bridge # 08924, MP 89.89.
