LA 1 /LA 415 Connector: Vessel Survey
The West Baton Rouge (WBR) Parish Transportation Authority, Louisiana Department of Transportation and Development (DOTD), and the Federal Highway Administration (FHWA) are gathering important information about vessel traffic along the Gulf Intracoastal Waterway (GIWW) at the Port Allen Canal lock. Please follow the link below for an opportunity to participate in this survey. The survey response period is February 13 – April 13, 2017.

LA 1 /LA 415 Connector: Vessel Survey

The LA 1/ LA 415 Connector Project
H.005121

The solution to Intracoastal Waterway Bridge
safety, evacuation and bottleneck issues.


Proposed LA 1 / LA 415 Connector




What is it?

A 3-mile road that bypasses the congested LA Hwy 1 corridor at the Intracoastal Waterway bridge and A 3-mile road that bypasses the congested La. Hwy. 1 corridor at the Intracoastal Waterway Bridge and provides another access point to I-10 and the Mississippi River Bridge. The four-lane divided roadway will extend south from I-10 at the La. Hwy. 415 exit over the Intracoastal Waterway to North Line Road and connect with La. Hwy. 1.

Overview:

La. Hwy. 1 is a principal artery of the national transportation system with an intermodal link to the nation’s energy supply, and oil and gas industries. It connects to Interstate 10 in West Baton Rouge, crossing the Intracoastal Bridge. This bridge is the only unrestricted access for La. Hwy. 1 in the region.

44,700 vehicles travel over the Intracoastal Bridge daily – far exceeding its design capacity. The bridge has an F rating and is more than 50 years old. The La. 1 route, which is also exceeding its design capacity, is also a hurricane evacuation route for some 120,000 people in south Louisiana. The I-10/ La. Hwy. 1 Connector is the solution to this critical traffic bottleneck.

Why an alternative route is critical:

Economic Viability & Development:

The population of West Baton Rouge is only 24,000, yet 44,700 vehicles travel on La. Hwy. 1 and over the Intracoastal Bridge daily. This shows the La. 1 roadway is a major transportation route for this region and south Louisiana.

Recently announced and expected projects at Westbank chemical plants total $2.7 to $3 billion, and will bring hundreds of jobs. This will further stress this already congested roadway. Approximately 35,000 trucks travel to and from the Dow Chemical Co. site straddling West Baton Rouge and Iberville Parishes on La. Hwy. 1 La. 1 annually, and planned projects/expansions coming to the site will bring an additional 7,000 trucks traveling La. Hwy. 1 annually.

A 1998 Executive Order by Gov. Mike Foster noted 95% of fish are shipped to market via La. Hwy. 1, sugarcane and vegetable harvests totaling more than$225,000,000 are transported over La. Hwy. 1, and the goods and services for the region’s oil, gas and petrochemical industry are transported via La. Hwy. 1.

Economic development and residential development of the area are stifled because of the traffic issues at the Intracoastal Waterway Bridge.

Peak hour congestion, accidents and maintenance projects in the area of the Intracoastal Waterway Bridge regularly create severe disruption to La. Hwy. 1 traffic flow. This cripples business efficiency in numerous ways.

In the last 50 years, the Baton Rouge area has more than doubled in population, and seen more than twice the growth of other Louisiana metropolitan areas. Long-term projections anticipate an additional 217,799 residents will live in the area by 2035, according to the CDM Smith Comprehensive Traffic and Toll Revenue Study commissioned by West Baton Rouge Parish.

The Baton Rouge region is poised for relatively strong economic growth and robust employment growth in the future due to the presence of large-scale, relatively stable industries, emerging industries and advantageous transportation corridors. A projected 383,474 jobs are predicted by 2035, according to the CDM Smith Comprehensive Traffic and Toll Revenue Study.

Safety:

The present Intracoastal Waterway Bridge is more than 50 years old and has exceeded its design capacity, with 44,700 vehicles traveling over it daily. Its present level of service is rated F, meaning it is well over capacity.

By comparison, the I-10 interchange at Breaux Bridge has 41,054 vehicles per day and the I-10/US 61 (Airline Hwy.) route at Sorrento has only 36,324 vehicles traveling it daily.

The only other route back to La. Hwy. 1 if the bridge is closed is a 53-mile journey on a winding 2-lane highway, and with traffic it becomes a 2-3 hour ordeal.

The proximity of the Intracoastal Bridge to the I-10 bridge is so close that when the Intracoastal Bridge is backed up with traffic, which happens daily, the traffic backs up on the I-10 bridge. This creates safety concerns on both bridges and La. Hwy. 1.

Emergencies & Evacuations:

The La. Hwy. 1 route over the Intracoastal Waterway Bridge is the hurricane evacuation route for some 120,000 people in seven parishes. It is estimated that evacuation would take 24 to 36 hours on this route!

La. Hwy. 1 is also the evacuation route if a release occurs at one of the many petrochemical plants in the region.

There is no emergency treatment center in West Baton Rouge or Iberville, so emergency patients must be transported to Baton Rouge hospitals. Traffic delays and Intracoastal Bridge lane closures can be life threatening for these emergency ambulance patients south of the Intracoastal Bridge.
