Street Reconstruction

The reconstruction of Jackson Street was part of the City’s Capital Improvement Plan for several years.  The reconstruction started several years ago at 36th Street with work extending south since then.  Recently the City desired to extend the reconstruction from 18th Street to south of 14th Street.

DGR Engineering was selected as the most qualified firm to provide the design services for this project.  This project included new utilities (sanitary sewer, storm sewer and water main), new sidewalks, paving and traffic signals.  An HMA street option was also presented in the plans which included a granular base and subdrains.  Improvements to W. 14th Street extended one-half block west.

A traffic study was completed by our traffic engineer subconsultant, Snyder and Associates, in the area of W. 14th Street and Jackson Street.  Improvements to the northeast corner radius of W. 14th and Jackson Street was also part of the plan.  The project was completed in three (3) stages with up to two (2) phases in a stage.

Project details including access during construction were discussed with local businesses.  DGR was involved in all aspects of survey, design and letting of the project as well as limited construction administration.
