City of Lake Charles, Louisiana Sallier Street Reconstruction LR0002 M.A. Project No. B6-17080-DA SCOPE OF WORK: The project scope of work for Sallier Street Reconstruction consists of the following brief summary: • Base Bid - Riverside Drive to Lake Street o Rehabilitation of an existing two-lane concrete roadway with a three-lane concrete roadway. The expansion of the roadway section is in response to LADOTD's extension of Nelson Road Extension and Bridge (Contraband Bayou Bridge), the large quantity of undeveloped property along Sallier Street and the volume of existing and projected traffic detailed under numerous traffic studies. The project scope will address major improvements in drainage, sanitary sewer and water services due to their required relocation. The Port of Lake Charles under a separate contract relocated the existing rail to the north side of Sallier Street in support of the LADOTD Nelson Road Extension and Bridge with ends at Riverside Drive. • Alternate No. 1 - Riverside Cul-De-Sac o The construction of a cul-de-sac at the southern end of Riverside Drive which was required to be dead ended as a result of the LADOTD Nelson Road Extension and Bridge (Contraband Bayou Bridge) project. • Alternate No. 2 - Riverside Drive and Lake Street Drainage Improvements o The installation of drainage improvements along Riverside Drive and Lake Street is a result of supporting the drainage infrastructure under the Sallier Street Base Bid scope of work.

The widening and resulting drainage improvements along Lake Street are a result of the Lake/Sallier interchange improvements to facilitate projected traffic counts through the interchange. • Alternate No. 3 - Walnut Grove Improvements o The rehabilitation of Depot Alley includes construction of a new interchange with Sallier Street and parking improvements within the Depot Alley right of way between W. Walnut Street and Jabez Drive.
