The 14th Street project is intended to enhance the pedestrian experience along the 12 blocks from Market Street to Colfax Avenue in downtown Denver.  The sidewalks will be widened and will include seating areas, elongated planters and planter pots, trees, street lighting, accent lighting and wayfinding signage.  Bulbouts will be installed at intersections to minimize pedestrian crossing distances.  An on-street bike lane will be added to connect the Cherry Creek trail and Civic Center Park.  The roadway paving will consist primarily of HMA mill and overlay and full depth HMA replacement where necessary.  The new corridor will be set up as shown in the picture above.  More information on the project can be found on the City and County of Denver website as well as a simulated video of the final product.

The Camp Garcia Entrance Road Project is located on the remote island of Vieques off of the coast of Puerto Rico. It is located in the Vieques National Wildlife Refuge owned and operated by the United States Fish and Wildlife Service. Construction occurred during the summer of 2009. The existing route was surfaced with a mixture of aggregate and soil depending on the location on the project. This project addresses both drainage issues as well as improving the surfacing throughout the route.  The project also improved overpasses to allow better seawater flow to mangrove forests that require seawater to thrive.

The Conzelman Road and Various Routes project is located in the Golden Gate National Recreation Area.The project began in March 2009 and was completed in October 2010. The project addressed multiple deficiencies in pavement, drainage, alignment and safety. The existing road was 22-24 foot wide with limited sight distances. With busses traveling through this area, existing narrow lanes were a safety hazard to the bicyclists whom frequent the routes.  Trails and viewpoints were reestablished for park visitors to be able to enjoy the aesthetics of the national recreation area.

Fernan Lake Road (Idaho Forest Highway 80) begins at the City of Coeur dAlene and runs through the Fernan Saddle in the Idaho Panhandle National Forest (IPNF).  This is a two-lane paved road which carries a variety of logging trucks, recreational vehicles, and residents automobile traffic was seeing increased traffic and high accident rates. It also lacked a modern stormwater system and showed signs of significant erosion on multiple slopes.  The new alignment helped to reduce the impact on the lake water quality and reconnected wetland areas that were previously divided by the roadway.  Much of the excavated material was reused on the project as a stable subgrade. 

The Mercer Corridor East Phase I-Fairview to Dexter Avenue project is a critical connector between the downtown business areas and the surrounding neighborhoods.  The project is intended to reconstruct pavements, replace infrastructure and utilities, increase mobility and transportation with improved modal access, improve congestion and safety, integrate land development, and strengthen economic connections.  More information is available at the project website.

The Mulligan Road project is located on the eastern part of the Fort Belvoir in Northeastern Virginia. This 1.62 mile section of roadway is a new alignment through Fort Belvoir that is being built to replace Woodlawn Road which was closed following the events of 9/11/2001. This new roadway will connect State Route 613 to State Route 1. The new roadway will consist of four new lanes, with a divided median, and shared use path for pedestrians and bicycles.  The project also inlcuded the installation of three major wildlife undercrossings and four small wildlife undercrossing.

The Northshore Drive Road and Drainage Improvements project consisted of an HMA overlay for the two lane road along the north side of Whatcom Lake (the water source for the City of Bellingham) along with sidewalk and stormwater system improvements. The project retrofits the entire street to meet requirements for both enhanced and phosphorus treatment of stormwater runoff, as well as completing the gap in the sidewalk between Dakin Street and the Silver Beach Store.Sustainable features include the installation of permeable sidewalks and bike lanes, creating additional access as well as promoting stormwater infiltration. The project also used local materials and reused the entire existing roadway structure as a base for the overlay.

This project will add multi-modal and pedestrian-friendly streetscape enhancements and street improvements on SE Pioneer Way in downtown Oak Harbor, WA. The project includes the removal and replacement of the entire surface street cross section, storm drainage conveyance system, and sanitary sewer system within the limits of the existing infrastructure. In addition, streetscape improvements include widening sidewalks, providing on-street parking, converting Pioneer way from a two-way to a one-way street, and adding social gathering spaces.  Additional information is available on the project website: http://pioneerway.blogspot.com/.

SH-75 in Idaho is the primary roadway used for North-South travel to Destination Resorts in Sun Valley, the Wood River Valley, and other recreational opportunities. This section of roadway is located in a mostly un-developed area. Due to the location along the Big Wood River there is abundant wildlife and wetlands in the project area. This project is the first part of a 27 mile improvement program between US-20 and Ketchum, ID. The purposes and benefits of the project are many, including increased capacity, increased transportation safety and increased access to surrounding areas, including new pedestrian and bicycle facilities.

The T.H. 95 Mill & Overlay Project is located Northeast of Minneapolis, Minnesota. The route runs parallel to the St. Croix River and the Minnesota-Wisconsin border and provides access to the William O’Brien State Park and St. Croix National Scenic Riverway.  The primary purpose of this project was resurfacing. A hot mix asphalt (HMA) mill-and-fill overlay was performed for a majority of the pavement. Improved storm sewer systems were installed and in Stillwater, MN improvements were made to the pedestrian facilities.  The project use recycled asphalt pavement and reused much of the existing pavement surface.

The projects rated for the City of Upper Arlington were part of their 2010 Street Reconstruction Program. The program was broken into two phases with five different streets being resurfaced.  Designs and construction was similar for all projects and all streets scored the same according to this assessment. The program seeked to improve mobility throughout the City including project activities such as pavement preservation and maintenance, utility upgrades and minor sidewalk improvements. The first phase included Edgevale Road and Glenmere Road and used an alternative method to traditional paving called Full Depth Reclaimation.  The second phase of the 2010 Street Reconstruction Program involved the paving of Sunset Drive, Inverness Way, and Eastcleft Drive and also used Full Depth Reclaimation.

The US 97: Lava Butte - S. Century Drive Section Project involves increasing the capacity of the existing two- and three-lane highway to four lanes (two lanes in each direction separated by a forested median), reconstructing the Cottonwood Road interchange, and constructing an alternative access to Lava Lands Visitor Center. The project was needed because the existing lane configuration of US 97 did not provide for adequate capacity for existing and forecast travel demand, nor were there safe ways to access and exit the highway at several key locations in the project area.

More information about the project can be found at the Oregon Department of Transportation's website.

The Wawona Road project is located in the southern portion of Yosemite National Park. This 28 mile project addresses multiple deficiencies in pavement, drainage, and safety. Throughout the life of the roadway, numerous roadway sanding applications over the winter months have overgrown the sides of the roadway. This project aims to reestablish the existing roadway as well as reconstructing the pavement section.

The East Entrance project began 53 miles west of Cody, Wyoming and over a four year period improved a 7.0 mile section of road.  Major improvements included increased lane width, sight distances, and pullouts for improved safety, upgraded stormwater systems, and reconstruction of failing pavements.  Some materials were reused, much of the required rock was acquired nearby, warm mix asphalt was used and new retaining walls and slopes were constructed to look like natural surroundings. 

The Madison to Norris project is located on the western part of the Grand Loop in Yellowstone National Park.  This 10 mile project addressed multiple deficiencies in pavement, drainage, alignment and safety. With larger recreational vehicles and busses traveling through this area, the existing narrow lanes posed a safety hazard. Additional seasonal traffic was also straining the capacity of the roadway with minimal pullouts and parking areas for visitor attractions. The project used native and non-invasive plants and restored natural habitats along the Gibbon River.  Materials from the existing roadway were reused when possible and were often used to create natural looking rock walls and cut slopes.
