Most of the roadway profile for US 301 and US 41 is flat, consistent with the surrounding terrain. The roadway profiles maintain minimum grades to drain roadway runoff, per FDOT design standards. The only locations where measurable vertical curves are incorporated in the roadway profiles are at the bridges where US 301 joins US 41 at 1st St, the DeSoto Bridge over the Manatee River, and at US 41 crossing over US 301 (10th St).
At the DeSoto Bridge, the roadway/bridge profile has a gradual slope on both the south and north approaches, with an elevation of about 5 feet above sea level. The original as-built bridge plans show a downgrade of 0.71%, then a 200-foot vertical curve leading to a flat 0% grade, increasing to a 3% grade over the river, and a 3% downgrade to a 0% grade. The crest vertical curve length over the Manatee River is 1,000 feet, with the sag vertical curves of 400 feet at both ends of the 3% grade. The K values are 167 for the crest curve and 133 for the sag vertical curves. The characteristics of the vertical curve are consistent with the posted and design speed of 45 mph.
Characteristics of the vertical curves along US 301 where it joins US 41 and where US 41 crosses over US 301 (10th Street) will be provided in a later version of this document.
There are no sidewalks along US 301 until the roadway merges with US 41 south of the DeSoto Bridge. Along US 41, five-foot-wide sidewalks are on both sides; however, they end just before
