Erie, Brotherton, Old Red Bank Road, Murray, and Red Bank

The existing Erie overpass above Red Bank will need to be lengthened to accomodate the new 6-lane Red Bank Expressway. The intersection of Brotherton and Red Bank Expressway will also change. The ability to connect Murray Ave with Brotherton factors into these plans.

The introduction of a through-traffic grid on Old Red Bank Road will also change this intersection.

A note on 3-lane roundabouts: In these scenarios where three-lane roundabouts are presented, one design/build option would be for ODOT to acquire enough land to build a three-lane roundabout, but only to build the outer two lanes in a first phase.  Then, if traffic warranted it, later — during a second phase of construction --  ODOT could add an inner lane (the third lane) on the inside of the circular roundabout at a modest cost or about $500,000.   For motorists and the  community, the advantage in this scenario would be that two-lane roundabouts are easier to navigate and consume less land, so if the Route 32 relocation from Fairfax to Eastgate is never built, traffic on Red Bank Expressway may never reach the higher level that would require the third lanes to be added by ODOT.

Alternative 1: Signalized Intersection

Red Bank Expressway is 9 lanes. A bike path runs along Brotherton. There is one lane from Red Bank Expressway onto Old Red Bank Road. The double-intersection of Murray and Brotherton is unchanged.


Alternative 2: 3-Lane Roundabout and 2-Lane Roundabout

There is a 3-lane level grade roundabout at the intersection of Brotherton and Red Bank Expressway. Brotherton leads to a 2-lane level grade roundabout at the convergence of Murray, Erie, and Brotherton. Old Red Bank Road is extended to intersect Erie to the east of the intersection before Arnsby.

Note the bike paths in this drawing.


Alternative 3: Exit Ramps and Two Roundabouts

There are exit ramps from Red Bank Expressway on either side, both leading to roundabouts. On the west side of the bridge, a new intersection is created: a 2-lane grade-separated roundabout. On the east side of the bridge, the exit leads to a 2-lane level grade roundabout where Erie and Murray meet. Access is removed to Brotherton Court. Old Red Bank Road is extended to intersect Erie to the east of the intersection before Arnsby.
