Bridge Replacement Project Underway on State Highway 138

October 26, 2010 - Northeastern Colorado/CDOT Region 4 - NEW CONSTRUCTION PROJECT - LOGAN AND SEDGWICK COUNTIES – The Colorado Department of Transportation (CDOT) recently began a bridge replacement project on US 138 in Sedgwick and Logan counties.

The project replaces the timber bridge on US 138 near milepost 14 as well as the culvert on US 138 near milepost 42 with concrete box culverts.  Both structures were originally constructed in 1930 and are two of Colorado’s poor bridges.

“Both structures are 70-years-old and have exceeded their life expectancy,” said CDOT Project Engineer Joel McCracken.  “While they are still safe for travel, it is important that we replace the structures to ensure safe and efficient travel in the future.”

To replace the structures, full closures of US 138 will be required at both locations for up to eight days to allow crews to set the concrete box.  Work has started at milepost 14 near Iliff with earthwork.  A full closure of US 138 at this location will begin at 7 a.m. on Wednesday, October 27th and continue until approximately 5 p.m. on Thursday, November 4th.  During the closure, motorists can take State Highway (SH) 55 south to I-76 and then I-76 west to Logan County Road (LCR) 55.  Once on LCR 55 go north to US 138.

Once US 138 reopens to traffic on November 4th, crews will still have some work to complete to finish the new structure.  As a result, motorists can expect single-lane alternating traffic from 7 a.m. to 5 p.m., Monday through Friday.  Work is expected to be complete at this location by the end of November 2010.

Following the full closure of US 138 near milepost 14, crews will begin work on US 138 near milepost 42.  CDOT expects the full closure of US 138 to begin towards the end of November 2010.  More information will be released as construction progresses.

Zak Dirt, Inc. is the contractor for this $593,000 project that is being funded through Funding Advancements for Surface Transportation and Economic Recovery (FASTER).  The entire project should be complete by early December 2010.
