Kronberg Park Multi-Use Walkway: Milwaukie, Oregon

Phase two of the Robert Kronberg Nature Park Master Plan involved the construction of a multi-use trail connecting the Kellogg Lake Bridge to the existing crossing of McLoughlin Blvd. at River Road and the regional Trolley Trail. Otak provided design services for phase two, which included an elevated structure for the portion of the trail that runs through a forested area. Otak worked with the City to find an alignment for the elevated section, planned to be 12 feet wide, that minimized the removal of existing trees. It was important to select construction methods that minimized the disturbance of the natural area while the trail was built.

A multidisciplinary Otak team performed geotechnical engineering; prepared construction documents, specifications, and cost estimates for the elevated section of the multi-use trail; and prepared an illumination plan consistent with the Kellogg Lake pedestrian bridge. Otak also provided bidding and negotiation support as well as construction support and inspection.

The Walkway provides a safe, off-road bicycle and pedestrian connection between the south side of the City of Milwaukie with downtown. Bicyclists, pedestrians and wheelchair users will no longer need to travel on the shoulder or in the traffic lanes of McLoughlin Blvd. to make this trip. The Multi-Use Walkway is a combination of at grade pathway and 600 feet of bicycle/pedestrian elevated structure. The Walkway includes an elevated combination viewpoint and rest stop midway along the corridor.
