Utilities <br />At the south end close to Innd Street point of <br />connection, there is a FPL transformer box with in the <br />limits of the 20 feet pedestrian easement. The Berger <br />A vart team will coordinate with FPL as well with other <br />utilities to solve any utilities conflict and will investigate <br />utilities requirement for future capacities that can be <br />incorporated with the bridge design. <br /> <br /> <br />3. Approach to Project <br /> <br />3.1. Assumptions <br />The City of Sunny Isles Beach is planning to construct a pedestrian and <br />emergency vehicle bridge connecting North Bay Road from Inn Street to 174(11 <br />Street. The proposed structure will span the existing <br />-, <br />canal and its landfalls with an approximate clear span => <br />length of 150 feet. The bridge deck will consists of <br />two thirteen-foot vehicular lanes and two seven-foot <br />wide outside shoulders, to be used as pedestrian/bike <br />path. The structure will be at grade bridge. <br />Intermediate supports in the channel will not be <br />permitted. <br /> <br />r:- <br /> <br />1m l <br />~W <br />~J,:..~;;:.;Q, <br /> <br />3.2. Structures <br /> <br />3.2.1. Pedestrian Bridge <br />Cross section of the proposed structure will include the ultimate configuration to <br />avoid future bridge expansion and increase of construction cost. <br /> <br />3.2.1.1. Future Use. <br />It is the intent of the City of Sunny Isles Beach to build the bridge to carry <br />vehicular traffic in both directions, with separate space at both sides of the <br />structure for pedestrian movements, after securing sufficient easement at the south <br />terminus of the bridge. <br /> <br />3.2.1.2. Original Use. <br />A present easement condition allows movement in the structure for <br />pedestrian/bike usage and small emergency vehicles only. Access to other type of <br />vehicles will be restricted by usage of concrete barriers at both ends of the <br />structure. <br /> <br />3.2.1.3. Alternative of Design. <br />Various design alternatives will be developed during the conceptual period. Each <br />alternative will be investigated for structural adequacy, functionality and <br />aesthetical attractive.
