CO 82 Grand Avenue Bridge

The Colorado Department of Transportation has started work to address the functional, structural & safety deficiencies of the Grand Avenue Bridge and bring it up to current standards for a four-lane bridge. Keywords: Studies, State Highways

CO 392 Access Control Plan

October 2006 - Recent and continued growth in along Interstate (I) 25, State Highway (SH) 392, and within the local communities that make up the North Front Range, has resulted in an increase in traffic on the SH 392 corridor. Traffic volumes in the area are expected to at least double in the next 20 years. Without changes to the corridor, this increase in traffic volumes will result in increased delay, higher levels of congestion, and an increase in the severity and number of accidents. The Colorado Department of Transportation (CDOT) has identified the need for an Access Control Plan (ACP) on this corridor to minimize the occurrence of these conditions.

CO 392 Environmental Overview Study (EOS)

The CO 392 Environmental Overview Study identified a transportation solution supported by local and regional planning partners that identifies right of way, which must be preserved for improvements. This plan will be used by planners to set aside right of way as development occurs along the corridor. The CO 392 EOS study limits are from CO 287 to the west to Weld County Road (WCR) 23 to the east. Keywords: Studies, State Highways, Construction Complete

Federal Blvd EA & FONSI, West 7th Avenue-West Howard Place

The Federal Highway Administration (FHWA), the Colorado Department of Transportation (CDOT), and City and County of Denver announce the availability of the Federal Boulevard Improvements project between West 7th Avenue and West Howard Place Environmental Assessment (EA) & FONSI.

Ports to Plains

This study was a joint effort by four state Departments of Transportation (DOTs) including Colorado, Texas, Oklahoma, and New Mexico. It includes I-70 from I-25 east to US 40/287 and then south along US 40/287 to the Colorado/Oklahoma border. The purpose was to create a Development and Management plan for the Ports to Plains Corridor, which outlines a proposed plan for the corridor and serves as an essential tool for securing federal funding for corridor development. It contains several elements that improve the transportation network’s ability to move people and goods. Nearly 1,400 miles long, the corridor consists of 511 miles of 4- to 6-lane roadway, 755 miles of 2-lane roadway, and 113 miles of roadway in metropolitan areas.

SH 7, Cherryvale to 75th Street EA & FONSI

Environmental Assessment (EA) May 2008 - This Environmental Assessment (EA) evaluates the environmental, social, and economic impact of the proposed action for State Highway (SH) 7 between Cherryvale Road and 75th Street (approximately 2.2 miles). For this study, the lead federal agency is the Federal Highway Administration (FHWA) and the Colorado Department of Transportation (CDOT) is the applicant. This EA evaluates the impacts of the Preferred Alternative. This is compared against the No-Action Alternative. Finding of No Significant Impact (FONSI) October 2008 - SH 7 is a principal east-west arterial roadway serving as a commuter and intra-regional facility (see Figure 1-1 and Figure 1-2). To comply with the National Environmental Policy Act (NEPA), an Environmental Assessment (EA) was conducted to evaluate the reasonable alternatives that address the purpose and need for the project and assesses the impacts of implementing the proposed improvements. Two alternatives, the No-Action Alternative and the Preferred Alternative (build alternative) were evaluated in the EA. The build alternative was identified as the Preferred Alternative.

SH 133 Carbondale Access Control Plan

The SH 133 Carbondale Access Control Plan will assess the existing and proposed access points along SH 133 within the study area and make recommendations for future changes if appropriate. Keywords: Studies, State Highways, Access Control Plan

SH 402 EA and FONSI

Environmental Assessment (EA) - July 2007 and Finding of No Significant Impact (FONSI) - January 2008- encompasses the 4-mile length of SH 402 although improvements are not needed for the area between SH 287 and CR 13C (St. Louis Avenue), which was widened by developers in coordination with the city of Loveland and the Colorado Department of Transportation (CDOT) under a Categorical Exclusion (CE).

State Highway 7 (Arapahoe Road) Environmental Assessment

State Highway (SH) 7, also known as Arapahoe Road, between Cherryvale Road and 75th Street is a major transportation corridor which serves the cities of Boulder, Lafayette, Louisville, and Erie as well as Boulder County. The Colorado Department of Transportation (CDOT) in conjunction with the Federal Highway Administration (FHWA) conducted an Environmental Assessment (EA) of this corridor to determine possible transportation alternatives. Keywords: Studies, State Highways

State Highway 60 Environmental Overview Study

The purpose of the State Highway 60 Environmental Overview Study (SH 60 EOS) is to identify the safety and mobility improvements necessary to address the future travel demand within the SH60 corridor for the year 2030 and to provide an overall strategy for CDOT and the local jurisdictions for right of way preservation and access control necessary to allow the future implementation of improvements with respect to changes in land use and rapid development along the corridor.
