Beltway – Edgewood Rd Interchange Safety Improvement Project Update

Here are some updates about the Beltway-Edgewood Interchange project.

The SHA has added the project to their website. Here is the link.

According to the SHA, topographic surveys and existing right of way information were received on December 11, 2015. The design team is currently working towards the 10% design milestone, which includes setting the alignments and typical section for the project.

According to the site, the purpose of this project is to improve safety at the I-495 and US 1 interchange and the US 1 and Edgewood Road intersection. The project limits extend from Cherry Hill Road to the inner loop ramp from eastbound I-495 to northbound US 1 for a distance of 0.251 miles. The scope of the project includes reconfiguration of the I-495 and US 1 interchange and realignment of the US 1 and Edgewood intersection to enhance safety.

The proposed improvements include:
• The removal of the eastbound I-495 to northbound US 1 inner loop ramp. This will eliminate the weave at the collector-distributer road traveling on I-495 and on US 1.
• The eastbound I-495 to southbound US 1 ramp will incorporate left turn movements to compensate for the removal of the eastbound I-495 to northbound US 1 inner loop ramp.
• The storage length at the same ramp will be extended to service higher traffic capacity.
• The entrance to Edgewood Road will be realigned to better accommodate drivers coming off the eastbound I-495 to southbound US 1 ramp.
• The existing northbound US 1 to eastbound I-495 ramp will be realigned to provide a smoother transition onto I-495.

Also, there is a strong possibility that the the Cherry Hill rd intersection improvement might be included in the scope of the project.

I’ll keep you posted as we get more update.

    With the relocation of the on ramp to the inner loop, would the city explore the possibility of reconnecting 47th pl to Niagara Rd?

    Hi Harry, It’s a good idea. We’ll explore it as the project moves forward. Thank you for the suggestion.

    I’m glad that the inclusion of the Cherry Hill Rd intersection is being considered. I think that would save the SHA some money from having to design/engineer/construct that separately, not to mention the saved time.

    I mentioned this concern before ( There’s a potential for worse congestion on the Beltway exit ramp to Route 1 as a result of southbound drivers cheating into northbound lanes. We know how traffic can back up for as far as a mile on that exit ramp, particularly when UMD has a major event (such as a football game). I live north of the Beltway, and so I’ve been fortunate to be able to bypass this congestion with a separate exit ramp.

    I see in the diagram that an extra lane is planned to be added to the exit ramp, and it certainly appears that there’s room to do this (there’s a lot of space on the right side of the exit ramp). That added lane would account for northbound traffic, and I see an additional lane for northbound traffic would begin within a few hundred feet of the intersection. Ideally, it would be nice if this second left-turning lane could begin even further in advance of the intersection. Granted, the eastbound entrance ramp onto the Beltway may interfere with this idea, but I hope the SHA can investigate whether it’s possible.

    I hope the SHA will take measures to discourage or flat out prevent southbound drivers from cheating into northbound lanes. Clear signs, lane markings (such as a solid line to separate the left southbound lane from the northbound lane), and even lane separators should be looked into.

    I realize this is in the early planning stages, but given that they’re working on the alignment now, I feel this is a good time to bring up such issues. Extending the second left-turn lane further down the ramp or installing lane separators would certainly have an impact on how things are aligned. This truly is a major project that will impact most if not all drivers in College Park. I hope the SHA takes the time and effort to evaluate all options, as we know there’s a lot of traffic that comes through this section of Route 1. This is a particularly bad place to underestimate the projected amount of congestion that can occur.
