The linked Rte 101 x-sections may be used to determine the net difference in NB and SB roadway elevations in the median. Regarding Concrete Barrier (Type 60C Modified), use the Rte 101 profile and superelevation and East Bayshore Road profile information shown in the project plans to determine the difference in roadway heights. For estimating purposes, the profile of East Bayshore Road not shown in the project plans may be considered flat.
