Most people who do not have access to JBLM park their car along mounts road / old pacific hwy as close as they can to the bridged and walk across it to the south west of the river, there is an area for the public on the south east and there is parking there as well.Police patrol the JBLM side and check for military ID or affiliation and an access permit from range control. With out those you will be asked to leave, Not sure if they are issuing tickets for trespassing, they have done that in the past.
it's sad, the nisqually never had much public access and about 50% of it was lost about 4 years ago when the railroad company put a rock wall and gate up below the trestle and the campground owner started charging for access to fish off the gravel bar above the trestle(i still can't figure out how it's legal, being that it's all below the normal high water mark). a few years before thurston county made the entire stretch of on their side of the old pacific highway bridge "no parking", despite the county seemingly putting in wider shoulders for the fishermen when they rebuilt the bridge in 1998.
