Pitkins Curve: Transportation Construction Management

MNS Transportation Division, Construction Management Team: Spotlight Project

Hazardous Rock-slides on One of California’s Landmark Motorways

The Pitkins Curve and Rain Rocks Shed project, located between Monterey and Cambria on California State Route 1 (Highway 1) was a major undertaking aimed at making a dangerous section of the scenic state highway safer for motorists.

The Pitkins Curve area of Highway 1 is part of an active landslide­; rock slides are a fact of life here, rather than an unusual occurrence. Its geological composition is particularly unstable. Rock slides repeatedly closed the original road and presented a significant danger to motorists.

Foreseeing that Pitkins Curve would continue to be a major safety issue and an access impediment for the millions of tourists traveling through the area each year, not to mention a major maintenance and cost issue, the California Department of Transportation (Caltrans) developed an innovative solution to the problem.

MNS Chosen for Lindero Canyon Road Bridge Improvements

The Lindero Canyon Road Bridge Improvements project is the third component of a three phase improvement plan to improve circulation and reduce traffic congestion along the Lindero Canyon Road corridor. The interchange is an important link for motorists to access commercial, industrial, and residential areas on both sides of the freeway. This project primarily modifies the existing bridge overpass at Lindero Canyon Road and Highway 101, and the approaching roadway. These modifications will include: removal of the existing center median; addition of a travel lane in each direction; removal and replacement of the existing exterior barriers with aesthetic treatments; northbound Lindero Canyon Road on-ramp median modification; and related grading, drainage, utility and traffic signal improvements.

The City of Westlake Village chose MNS to provide construction management services for this project.

Quails in Concrete Stamping at Willow Road
Concrete Art on California’s Highways

Whether you know it or not, you’ve seen concrete stamping before—from freeway structures we use every day to landmarks of ancient architecture, this technique for molding or impressing scenes and patterns into wet concrete is used to add visual interest to what could otherwise be seen as boring slabs of cement.

Rocky Creek Viaduct: Safer Transportation Infrastructure

In April of 2011, a landslide damaged a 200-foot portion of California State Route 1—a historic part of our state’s transportation infrastructure—along the steep cliffs between Bixby Bridge and Rocky Creek Bridge, south of Monterey and Carmel-by-the-Sea.

The hillside was stabilized right away using a soil nail wall, but the highway had to be reduced to one lane with signal-controlled traffic through the area. The Rocky Creek Viaduct, a 600-foot bridge structure, is being constructed to completely replace the roadway adjacent to the repaired slope. Creating a bridge here means future landslides won’t affect the Viaduct area—any slide material will pass between the bridge and the hillside, keeping motorists safe and preventing further expensive damage to this stretch of road.
