States traversed: Mississippi, Alabama, and Florida
US Route 98 runs from Natchez, Mississippi, southeast to Palm Beach, Florida, and can be imagined in three different sections with different characteristics. US Route 98 starts as an inland route, running from Natchez east through Hattiesburg, Mississippi, and southeast to Mobile, Alabama. From Mobile, the second section exists as a route immediately adjacent to the Gulf Coast through Florida's panhandle, passing through tourist destinations like Panama City. Then, the final segment dives southeasterly, cutting an inland path across the Florida Peninsula through places like Lakeland, Sebring, and Okeechobee. US Route 98 cuts through West Palm Beach, passing by West Palm Beach's International Airport, to end at Florida Route A1A in Palm Beach. The westernmost stretch of US Route 98 in Mississippi, for reference, is concurrent with US Route 84 up to its western end in Natchez at US Route 61.
My US Route 98 shield in the shield gallery comes from this sign assembly above, along US Route 43 at that route's southern end. The exact location on Google Maps is here. The arrows point to an access road to a highway that doesn't carry US Route 98 proper; instead, it carries an alternative US Route 98 route for trucks, using the northernmost bridge over the Mobile River in the city of Mobile. November 1, 2016, was the date I took the photo above, during my second visit to the Mobile area. Since this photo doesn't really relate to US Route 98 proper, here's another photo of US Route 98 below: it's the first westbound trailblazer in Alabama, for traffic having just crossed the state border out of Florida.
Alabama likes to use these skinnier shapes for their US Route shields. For consistency in my sign collection, I like to use the more traditional, rounder, shape whenever possible. The photo above was taken in October 2014, as part of my first trip to the Gulf Coast and the Mobile area. It held a place in my official sign collection until I replaced it with the newer photo, which I preferred because it didn't have the skinny US shield shape used by Alabama.
Here's another photo from US Route 98 in Mississippi, too:
