CP243 Interlocking Project
The CP243 Interlocking Project will construct a new four-track interlocking, a powered switch and signal system that allows trains to move from one track to another. The new interlocking is approximately 3,200 feet long, located approximately 1.5 miles east of the Walk Bridge on the New Haven Line (NHL) between East Norwalk and Westport.
The project includes:
• Six new switches
• Track replacement and realignment
• New catenary structures
• Overhead catenary system modifications
• Communications and signal systems
• Drainage improvements
Anticipated Start DateFall 2017
Construction Duration3.5 Years
Estimated Construction Cost$210 Million
What Does CP243 Mean?
‘CP’ means control point‘2’ refers to the New Haven
Commuter Line‘43’ is the nearest mile post on the rail line, marked from Grand Central Terminal
WALK BRIDGE PROGRAM | 2017
A railroad switch is a set of tracks that create a junction, that when moved allows for trains to change from one track to another.

Potential Mitigation Measures
• Maximize daytime work
• Ongoing noise monitoring
• Low impact equipment
• Suppression of equipment noise
• Limit equipment idling time
Noise and Vibrations
The Walk Bridge Program understands that noise and vibrations which will occur as part of the CP243 Interlocking Project and may be of concern to the Norwalk community. The project will maximize daytime work to the extent possible. Night work is required because most track outages are available at night. To best minimize noise and vibrations, a construction coordination plan is being developed that will identify ‘sensitive receptors,’ establish baseline noise and vibration levels, implement
monitoring and mitigation techniques. The plan is a living document which will be developed in coordination with stakeholders. As the project progresses, unforseen nuisance noise will be evaluated and mitigated to the extent possible.
