South Madera 6-Lane
Project Description
The California Department of Transportation (Caltrans) proposes to widen State Route 99 in Madera County from just north of Avenue 7 to Avenue 12 (post miles 0.1-8.1). One lane would be built in each direction on the highway median to create a six-lane highway. Additionally, the existing lanes and shoulders of State Route 99 would be rehabilitated, and a concrete median barrier would be installed along with an auxiliary lane at the Avenue 12 northbound off-ramp.
Project Benefits
Purpose
The purpose of the project is to reduce congestion by increasing capacity, improving connectivity of the highway system, and preserving acceptable facility operation.
Need
The State Route 99 highway within the project limits currently operates at acceptable levels of service during peak traffic hours and will continue to do so through the year 2027 without any improvements. However, by the year 2047, the highway mainline will have insufficient capacity to accommodate the forecasted traffic demand under the No-Build Alternative, and delays will significantly increase.
The existing (2019) level of service for the northbound and southbound lanes is Level of Service D. In the year 2027, the levels of service will be D to E for both the northbound and southbound lanes. Twenty years later, in the year 2047, the level of service will deteriorate to a level of service F for both the northbound and southbound lanes if the highway is still only two lanes in each direction. The existing annual average daily traffic within the project limits is about 80,500. In the year 2027, the annual average daily traffic is forecast to be 90,500. In the year 2047, the annual average daily traffic is forecast to be 127,000.
