According to JOSM MapWithAI US Addresses data source, This should be "Martingale Drive", not divided into "East" and "West". I've updated the road names and house addresses around it
Double checked source with Douglas County Assessor's website: https://apps.douglas.co.us/assessor/web/#/ and specifically this pdf: https://apps.douglas.co.us/realware/SectionMaps/TWP2233/DC_2233_20.pdf
That's also how Apple Maps, Mapquest, and Google Maps have it. Can also confirm with street signs.

Also there are some "tiger" tags on the streets and not sure if i should remove or fix those.
