Featured Project: Trinidad I-25 to Main Street Construction
Expected Completion Date: Summer 2009
In April 2007, Lawrence Construction Company began demolition and reconstruction of aging infrastructure over Main Street and the Purgatoire River in Trinidad, Colorado. In addition to improving access between New Mexico and Colorado’s Front Range, this regional project is also expected to attract new business and create positive economic benefits for existing small business in Colorado.
Designed for the 21st century with the latest safety standards in mind, reconstruction of I-25 in Trinidad will also incorporate aesthetic features that tie into Trinidad’s historic architecture and natural surroundings. While the new design incorporates traditional features that are characteristic of Trinidad, the colors of the bridges, viaducts, and retaining walls will match surrounding stone bluffs adding even more aesthetically-pleasing qualities to the structure.
Construction plans include upgrades to Purgatoire River Park, an extension of the Purgatoire River Trail, a new parking lot located under the viaducts, a new AMTRAK shelter, safety upgrades for City streets at several railroad crossings and a noise wall located on the west side of I-25 from Commercial Street to Goddard Avenue. Overall, the project is successfully underway and is expected to be complete by the summer of 2009. For the latest information and more, visit www.historictrinidad.com.
Status: Opened for traffic October 25, 2007
Begun in March 2006, this design-build project was completed on-schedule and within budget with the most important feature being increased traffic safety and efficiency when traveling northbound on E-470 to westbound I-70. Completion of Ramp H construction marks the latest in E-470 Public Highway Authority’s plan to create a “fully directional interchange unimpeded by traffic signals” that will eventually allow drivers to bypass traffic lights no matter which direction they're headed. Citizens love it because they can travel quickly, more safely and conveniently through an interchange that used to be known for traffic accidents.
As a native Colorado general contractor with over 80 years of experience, Lawrence Construction Company is proud to be a part of designing and constructing projects, like this one, that provide obvious value and immediate benefit to the citizens of Colorado, and the E-470 / Gun Club Road corridor is the latest example of ongoing commitment to such quality and service.

Owner: City and County of Denver
Status: Completed May 2008
Named "Globeville" for its Eastern European inhabitants of the late 1800's, this South Platte River valley community is located in the north-central area of Denver.
Lawrence Construction Company was chosen by the City and County of Denver to lead as the general contractor on a final construction phase to remove approximately 200 acres of highly urbanized lands in north Denver from the 100-year floodplain. Construction is expected to be complete in the spring of 2008.
As general contractor on Phase III for South Platte River improvements, Lawrence Construction Company is implementing a design/build project that will redirect the flow of the South Platte River. By constructing a new diversion channel after removing the old diversion dam to bed level, the riverbed can be excavated from the downstream side of the new diversion lowering the invert of the River from the 100-year floodplain.
In just 10 days, the company has successfully removed and replaced a Union Pacific Railroad bridge complete with new track. This new and improved structure has six round concrete piers as compared to 20 wooden piers from the old bridge.

Questa, New Mexico
Owner: Molycorp, Inc.
Status: Completed November, 2006
Molycorp, the nation's fifth largest producer of molybdenum, teamed with Lawrence Construction Company to enhance protection on New Mexico's Highway 38. This unique berm enhancement project was a success for both companies, Molycorp and Lawrence Construction, whose work to enhance the berms at the base of the Middle Pile, Sulphur Gulch, and Sugar Shack South increased the owner's capacity on ore recovery and created Molycorp's most accessible non-underground source for molybdenum.
US 40 Berthoud Pass (Phase 3) - Berthoud, CO
Status: Completed 2006
This major reconstruction was the final phase to widen U.S. 40 on the east side of Berthoud Pass and won project superintendent, Mike Rachubinski, an award from the Colorado Contractor's Association. Adding a climbing lane to the lower two miles of the existing two-lane highway, the project included shoulder widening, adding new retaining walls, constructing four permanent sediment capture basins, and a new storm drainage system to the highway. A large-animal crossing was also constructed under the highway.
Originally constructed in 1941, this National Monument towers more than 200 feet above the Eagle River canyon floor in Red Cliff, Colorado where it is destined to remain for years to come. This project included widening and replacing the structure's deck, carefully removing lead paint, and spending considerable work on abutments, girders, and bridge rail. Recognized by the National Bridge Alliance and the American Institute of Steel Construction, Lawrence Construction Company was able to maintain this Prize Bridge's original beauty and character while strengthening and updating it to current safety standards.
Status: Completed 2003
At the inception of this project, Lawrence Construction Company approached CDOT with a proposed alternative: To build a superstructure girder type bridge that would replace four existing structures at Tejon and Nevada Avenues. Lawrence Construction Company's proposed value engineering approach for the alternative girder type included all cost of preliminary and final engineering and cost estimating. By working with CDOT staff and their consultant, the redesign and associated construction cost saved $600,000 on the project, minimized traffic detours, and eliminated scaffold requirements thereby significantly reducing safety impacts to the project.
Status: Completed 2002
Located on State Highway 86 southeast of Denver in Douglas County, Mitchell Gulch Bridge was a 50-year old box culvert carrying approximately 12,000 commuters Monday through Friday. In an ambitious attempt to replace the ailing structure while minimizing traffic disruption, Lawrence Construction Company teamed with Wilson & Company in intense planning to coordinate the demolition of the old bridge and to replace it in one weekend. Using precast elements from Plum Creek Structures, the project team met with success: Careful coordination began at 7 p.m. on Friday, August 23, 2002 and by Sunday at 5 p.m. a new bridge was open to traffic.
This award winning project was expected to take 2 or 3 months to complete but because Lawrence Construction Company used precast elements to fabricate 90 percent of the 40-foot-long bridge and utilized steel piles readied ahead of time, the job was finished in 48-hours. Amazingly, the Lawrence & Wilson team could have been completed the job earlier, but modifications were made during construction to ensure that substructure pieces fit perfectly.
Status: Completed October 2000
Lawrence Construction realigned the Arkansas River channel with retaining walls, channel floor slabs, and water features to bring the river back to downtown Pueblo in an elegant display known as the Historic Arkansas Riverwalk Project (HARP). This award winning project had architecturally pleasing features that included elegant stone masonry, intricate ironwork, and a pedestrian fence railing system in addition to key signature features such as Kelly Falls, the Farely/Reilly Fountain, and bridges at Victoria Avenue, Union Avenue, and Main Street.
Status: Completed 1999
This APWA award-winning bridge made for Roche Construction at SH 36 and 96th Street set the standard for architectural integrity for bridge construction in the state of Colorado. Nine additional bridges and 4 box culverts were built in relation to this first project using the same style of architectural treatments such as rock veneer and attractive fencing.
Features of this project included utility construction, water main, sewer main, storm interceptor lines, interchange lighting, intersections with traffic signals, concrete flatwork, HBP paving, and construction of State Highway 30.
Status: Completed 1998
Located on the east side of Santa Fe (SH 85) between Belleview Ave. and Mineral Ave. in Arapahoe County, this Segment 1 (southwest corridor) light rail project consisted of building 3 railroad light rail bridge structures for the Regional Transportation District.
