Proposed Improvements

The project will realign the southbound and northbound I-95 off ramps to eliminate the existing yield condition. Additional right and left turn lanes will also be constructed at the intersection of the I-95 ramps and Temple Avenue. The signalized intersection at the interchange will be removed and replaced with a roundabout.  The existing crossover on Temple Avenue that is located east of the intersection will be closed to increase driver safety.

The proposed roundabout includes two lanes of circulation and a continuous bypass lane on the west bound approach. Both the northbound and southbound I-95 off-ramps are extended and improved to provide motorists greater distance and improved curvature for transition from the high speed mainline to the arterial. The northbound I-95 off-ramp is improved to provide for a free-flow movement and eliminate the existing yield controlled condition.

The relocation of the intersection to the west will provide better operations at the I-95 northbound/southbound merge point by increasing the distance between these points, improving roadway geometry, and allowing for greater transition and storage area between the merge point and the intersection.

To accommodate the design year 2036 traffic projections, which show additional capacity is needed, the central island is designed to accommodate construction of a third inner lane to the westbound approach without expanding the roundabout’s footprint. Future expansion would include an additional entry lane (two entry lanes into the roundabout and a single bypass lane) on the westbound approach and an additional departure lane on the eastbound approach.

The proposed layout was approved and adopted by the Colonial Heights City Council on December 13, 2011.

A design public hearing will be held September 12, 2013.
