The project is related to
the state highway 193, Dauphin Island Causeway that is often known as Dauphin
Island Parkway (DIP). It provides ground connections between the mainland of
mobile county and Dauphin Island. The effect of erosive forces such as storm
surge, tidal actions, ship wakes and coastal losses is having a severe impact
on the ecosystem (Qld. gov. au, 2018). The main objective of the present
section is to develop a transportation part such as developing a shoulder
having 12 ft that enables to use the parking lane and to ensure the emergency
evacuation in the selected area in case of any storm event or hurricane. The
emergency evacuation must be designed in such a way that reduces the losses and
saves the lives of people living in these areas (Qld. gov. au).
Team organization and function of Transportation
The proposed solution will
be helpful to reduce the life losses in the selected areas. The main goal of
the project is to improve the resiliency as well as durability of the Dauphin
Island Causeway. The solution will enable to safeguard and enhance the long-term
sustainability of the coastal area habitat surrounding in the Dauphin Island
Causeway.
Personal contribution of Transportation
My contribution to the
project is to design a new transportation system that will be more efficient as
compared to the previously existing system.
1. The new transportation
system design will require less evacuation time and reduces the recovery time
from an event of a storm.
2. The new transportation will
be designed in such a way that it will protect the roadway from any kind of
damage and erosion during the event of a storm.
3. The safeguard of the roadway
will be from the Sea level rise.
Figure 1: New Road design
Solution of Transportation
The new design of roads is
proposed as the shoulder to seawater and divided into the walkway and parking
lane. The width of the road will be sufficiently higher as it constitutes of
two lanes including walkway lane and parking lane. In the sea the breakwater
will be introduced at optimized distance to reduce the speed of water, after
that region of sand will absorb a higher quantity of water in case of any
erosion, right after sand land there will be a region of vegetation, the road
will be of two parts and then the there will be marsh. The local habitat will
be restricted to live at sea to reduce the consequences of the erosion process.
Conclusion on Transportation
The new design will be
further modified to introduce a parkway in the west and it will not encroach on
the existing marsh. The design will include a road between marsh and sea wall.
The water level sensors are also proposed to be used to measure the water
level. In case of any hurricane or erosion, the sensors will alarm the
situation. The process of evacuation will be added by the implementation of
alarms.
