Figure 3.3 Route Alternatives Cyntheanne Road Planning Study 18
3.4.1 Alternative 1 – Central Alternative • The existing Cyntheanne Road to the north would be connected to the existing Cyntheanne Road to the south. Currently, there is about 7,500 feet of missing roadway. The Central Alternative provides the most direct path between 96 th Street and I-69 and forms a new total length of approximately 4.4 miles for the Cyntheanne Road Corridor. This alternative would severely impact the wetlands between the two segments of Cyntheanne Road as it will pass directly through the wetlands and require the construction of a bridge. Furthermore, a federal environmental law states that if there are wetland impacts then alternative routes need to be studied and used, if possible. A minimum of a new 1,100 foot bridge will need to be constructed at a significant cost. This is the costliest alternative as it will cost $24.1 million for two lanes and $35.3 million for four lanes. The new section of roadway between the existing portions of Cyntheanne Road will be subject to poor soil conditions, which will require costly solutions. These solutions include fill materials, removal of the organic material through excavation, or lengthening of the bridge structure. The exact limitations of the site’s soil have not been determined at this time. Soil samples from nearby bridges suggest poor building conditions, which result in significant risk to the project budget and the finished product. This alternative is the most direct solution, but should be considered for further environmental study prior to selection. 3.4.2 Alternative 2 – Eastern Alternative • The existing Cyntheanne Road would connect with SR 238 and Connecticut Avenue to the east and then tie into the existing Cyntheanne Road to the south. The Eastern Alternative would be approximately 5.5 miles in length, of which approximately one mile can be milled and resurfaced. The remaining portion of the roadway would need to be reconstructed to replace the existing pavement to match the typical section of choice while also fixing alignment issues. This alternative provides a more winding route to I-69 from 96 th Street, but uses existing right-of-way for most of the length. This alternative utilizes two recently reconstructed bridges, which would need to be widened to accommodate a sidewalk and multi-use path for Typical Section A, or additional travel lanes for the Typical Section B. While bridge widening is not mandatory, the safety of pedestrians would be compromised due to the relatively narrow bridge as compared to the Cyntheanne Road Planning Study 19
